RIDOT issues oversize and overweight permits online. Without a permit a Rhode Island vehicle may be 102 inches wide and 162 inches (13 feet 6 inches) high; a single vehicle may be 40 feet long and a semitrailer 53 feet, with semitrailers over 48 feet 6 inches limited to designated routes. Axles are capped at 22,400 pounds single and 36,000 pounds tandem, and gross weight follows the bridge formula up to 80,000 pounds. A non-divisible single-trip permit costs $40 under R.I. Gen. Laws § 31-25-21, and RIDOT's rate chart lists $300 at 130,000 pounds or more; an annual construction-equipment blanket permit costs $400. Escorts start at 12 feet wide, 80 feet long or a 15-foot overhang.
Rhode Island legal limits (no permit needed at or under these)
- Width
- 8.5 ft§ 31-25-3 caps the total outside width of a vehicle or its load at 102 inches; the fine is $100 per inch over width.
- Height
- 13.5 ft§ 31-25-4 caps a vehicle including load at 162 inches (13 feet 6 inches); the fine is $500 per inch over height. RIDOT says a permit over legal height may need a route survey, typically does on non-interstate routes over 13 feet 6 inches, and always does at 14 feet or higher.
- Gross weight
- 80,000 lb§ 31-25-13 caps any single axle at 22,400 pounds (an axle load being all wheels between two parallel planes 40 inches apart). § 31-25-14 caps tandem axles spaced 8 feet or less at 36,000 pounds and applies the bridge formula W = 500[(LN/(N-1)) + 12N + 36] to any group of two or more axles, with an 80,000-pound overall maximum except under permit. Overweight fines are $125 per 100 pounds for axle violations, and under § 31-25-16 $125 per 500 pounds for gross violations on vehicles over 10,000 pounds, plus $1,025 above 104,800 pounds and $2,500 above 130,000 pounds.
Axle weight limits
Gross weight is one ceiling; each axle group carries its own limit, and a load can be legal on gross weight yet overweight on an axle. Exceeding any of these needs an overweight permit.

Permit fees
- Single trip
- $40 (R.I. Gen. Laws § 31-25-21(c) sets a $40 fee for each non-divisible single-trip permit. RIDOT's OSOW User Guide rate chart lists the statutory fee as $40 under 130,000 pounds gross and $300 at 130,000 pounds or more, plus an enhanced access fee kept by the portal operator: $4.50 on a sub-130,000-pound trip, and $12 (subscriber) or $20 (pay-as-you-go card or eCheck) on a heavier trip. A single-trip permit is valid for five days from the requested start date, a round trip needs a separate permit for each travel day, and every application is reviewed by RIDOT before issue.)
- Annual eligibility
- The $400 annual blanket permit (§ 31-25-21(d) and (e)) covers intrastate moves of non-divisible construction equipment, boats or marine assets under 130,000 pounds, on a fleet of company-owned vehicles listed on the permit, at 55 to 80 feet overall length, up to 12 feet 4 inches wide, up to 25,000 pounds per axle and 130,000 pounds gross. It runs one year from issue, allows day and night travel on state highways, requires a flashing amber light above the highest point and red flags on all extremities, and may not be used over the Blackstone River Viaduct (I-295) or the Kingston Road bridge (I-95) or through lane-width reduction zones. Separately, Annual Divisible Load (ADL) permits let a single vehicle carry divisible loads above bridge-formula weight, overweight only and never oversize, expiring March 31 regardless of issue date.
Single-trip permit fee schedule
A single-trip permit stacks a base fee with a weight-tiered maintenance fee, and the heaviest loads add a supervision fee.

Escort thresholds
What the escort itself has to be
Hitting the threshold is only half of it. The escort vehicle, its equipment, its driver's certification and where it rides are all regulated, and the carrier is the one holding the permit when they are not met.
- General
- Escort vehicles must be at least compact-car size, keep visual and two-way radio contact with the permitted vehicle, run flashing yellow lights above their highest point and low-beam headlights at all times. RIDOT's FAQ adds that a permit reviewer may require escorts whenever the circumstances call for it.
Escort rules beyond the thresholds
Knowing when you need an escort is half of it. These are the Rhode Island rules on who may run one, what the vehicle has to carry, and how the move is conducted.
- General
- Escort vehicles must be at least compact-car size, keep visual and two-way radio contact with the permitted vehicle, run flashing yellow lights above their highest point and low-beam headlights at all times. RIDOT's FAQ adds that a permit reviewer may require escorts whenever the circumstances call for it.
Conditions attached to every permit
The standing conditions Rhode Island writes into the permit itself, which apply whether or not they are printed on your copy.
- Summary
- The permittee indemnifies the State, is liable for damage to roads, signals and bridges, and must carry liability and property damage insurance sufficient for any claim; RIDOT may require a certified check, bond or other security where a move could damage highway facilities. RIDOT permits cover only state-maintained roads: the Mount Hope and Newport bridges need Rhode Island Bridge Authority permits and city or town streets need local permits. Permits and their documents ride in the vehicle. A carrier caught without a required permit or over its permit limits three times in a year loses permit privileges for up to 30 days, and up to 90 days for further violations; operating beyond a permit voids it.
Travel restrictions
- Daylight only
- Yes (290-RICR-40-00-1 section 1.5.8 allows most permitted vehicles on designated routes from 30 minutes before sunrise to 30 minutes after sunset, with no night travel except for overweight-only envelope vehicles able to keep up with traffic. Annual blanket permits are the statutory exception: § 31-25-21(e) makes them valid day and night on state highways.)
- Curfews
- Vehicles over 8 feet 6 inches wide, over 80 feet long or over 130,000 pounds may not travel on freeways and arterial roadways from 7:00 to 9:00 a.m. or 3:00 to 7:00 p.m., Monday through Friday (§ 31-25-21(f)(1)). Mobile or modular homes over 12 feet wide, construction equipment over 13 feet wide and cranes may travel on all of I-195 and on I-95 from the Massachusetts line to Route 37 only between sunrise and 7:00 a.m. and between 9:00 a.m. and 3:30 p.m. (290-RICR-40-00-1 section 1.5.8(B)).
- Weekend / holiday
- No Saturday, Sunday or Monday travel, day or night, on Memorial Day, Victory Day, Labor Day, Dr. Martin Luther King Jr. Day and Columbus Day weekends; no travel Wednesday through Sunday of Thanksgiving week; no day or night travel, and none the previous night, on Independence Day, Veterans Day, Christmas Day and New Year's Day; no Saturday night or Sunday travel at Easter (§ 31-25-21(f)(3)).
- Wind / weather
- No travel when road conditions, weather or visibility make it hazardous; a vehicle already underway must exit at the first available location and park until conditions improve (290-RICR-40-00-1 section 1.5.9). § 31-25-21(f) makes all permission to travel subject to weather and road conditions.
- Daylight hours rule
- 290-RICR-40-00-1 section 1.5.8 allows most permitted vehicles on designated routes from 30 minutes before sunrise to 30 minutes after sunset, with no night travel except for overweight-only envelope vehicles able to keep up with traffic. Annual blanket permits are the statutory exception: § 31-25-21(e) makes them valid day and night on state highways.
- Weekend
- 290-RICR-40-00-1 section 1.5.7 says permit travel is authorized Monday through Friday with no Saturday or Sunday travel 'under the agreement', language carried over from the New England Transportation Consortium procedures the rule adopts. The statute's holiday schedule and RIDOT's FAQ list only the holiday restrictions above; confirm weekend movement on the permit itself.
- Weather
- No travel when road conditions, weather or visibility make it hazardous; a vehicle already underway must exit at the first available location and park until conditions improve (290-RICR-40-00-1 section 1.5.9). § 31-25-21(f) makes all permission to travel subject to weather and road conditions.
Superload and beyond-permit review
Loads past the standard single-trip permit thresholds get individual state review rather than an off-the-shelf permit.
RIDOT requires an independent third-party analysis of every structure on the requested route for permit vehicles weighing 200,000 pounds or more, depending on route as RIDOT determines. The fee tier changes earlier: RIDOT's rate chart prices a single trip at 130,000 pounds or more at $300, and § 31-25-21(e) lets RIDOT approve a single-trip non-divisible permit above 130,000 pounds on application and good cause. 290-RICR-40-00-1 defines 'extra large vehicle or load permits' (moves beyond consortium limits) and requires those applications at least five working days ahead.

- Escort notes: general
- Escort vehicles must be at least compact-car size, keep visual and two-way radio contact with the permitted vehicle, run flashing yellow lights above their highest point and low-beam headlights at all times. RIDOT's FAQ adds that a permit reviewer may require escorts whenever the circumstances call for it.
- Escort notes: bridges
- For a permitted vehicle over 9 feet wide, the owner must arrange with police to halt traffic at one end of a bridge before crossing it.
- Escort notes: spacing and lanes
- Oversize permitted vehicles traveling the same direction keep at least 1,000 feet apart, and loads over 12 feet wide use the right lane when two or more lanes are available.
- Seasonal permits note
- RIDOT offers no seasonal or harvest permit; its three permit types are the single-trip non-divisible permit, the annual construction-equipment blanket permit and the Annual Divisible Load permit (April 1 to March 31). Local authorities may by ordinance restrict vehicle weights on their own roads for up to 90 days a year when weather or deterioration threatens the road, once signs are posted.
- Permit conditions: summary
- The permittee indemnifies the State, is liable for damage to roads, signals and bridges, and must carry liability and property damage insurance sufficient for any claim; RIDOT may require a certified check, bond or other security where a move could damage highway facilities. RIDOT permits cover only state-maintained roads: the Mount Hope and Newport bridges need Rhode Island Bridge Authority permits and city or town streets need local permits. Permits and their documents ride in the vehicle. A carrier caught without a required permit or over its permit limits three times in a year loses permit privileges for up to 30 days, and up to 90 days for further violations; operating beyond a permit voids it.
- Statute note
- Legal dimensions and weights are in R.I. Gen. Laws chapter 31-25 (§§ 31-25-3 to 31-25-7, 31-25-13 and 31-25-14). RIDOT's permit power and the single-trip and blanket fees are in § 31-25-21, divisible load permits in § 31-25-22, and permit conditions in § 31-25-23. RIDOT's procedures are 290-RICR-40-00-1, refiled without text changes effective January 4, 2022; parts of that text (the $20 trip fee and $100 blanket fee in section 1.4.4, and applying at the DMV) predate the current statute and online system.

Legal limits without a permit
Width and height are capped by statute including the load, with fines charged per inch over. Length depends on the configuration: single units, semitrailers, longer semitrailers limited to the Interstate and designated roads, and twin trailers each have their own limit, and loads may hang a set distance past the front and rear.
Axle loads, the bridge formula and a gross cap govern weight, and Rhode Island's tandem limit sits above the common figure. Overweight fines climb with every increment over the axle and gross limits.
What permits cost
R.I. Gen. Laws § 31-25-21 sets the single-trip fee, and RIDOT's rate chart adds a higher tier for the heaviest loads. The portal operator keeps a separate enhanced access fee on each permit, which depends on the weight tier and on whether you pay as a subscriber or by card or eCheck. Subscriber accounts also pay a yearly billing fee.
The construction-equipment blanket permit has a flat yearly price. Annual Divisible Load fees for Rhode Island trucks are built into the registration fee, while out-of-state trucks pay a flat trailer fee or a charge for each block of weight over the legal limit, up to a cap.
Escorts
Escort counts follow width, length and overhang bands set in RIDOT's rule, with two escorts at the widest and longest bands. Height above the legal limit and very heavy axle loads also call for an escort, with the count set on the permit, and a reviewer can add escorts whenever conditions call for it.
Building moves need two escorts and a police escort from each city or town on the route. Escort vehicles run flashing yellow lights and headlights and keep radio contact, and for wider loads the owner arranges police to halt traffic before a bridge crossing.
When permitted loads can move
Most permitted loads move in daylight only, from shortly before sunrise to shortly after sunset. Wide, long or very heavy loads stay off freeways and arterials during weekday morning and afternoon rush hours, and wide mobile homes, construction equipment and cranes get narrower windows on I-195 and part of I-95.
Holiday blackouts cover the long weekends around Memorial Day, Victory Day, Labor Day, Martin Luther King Jr. Day and Columbus Day, most of Thanksgiving week, and several single holidays. The blanket permit is the exception that allows night travel on state highways.
Restricted bridges and superloads
The Washington Bridge on I-195 in Providence carries a reduced weight limit and bars oversize vehicles until RIDOT's posted end date. The blanket permit cannot be used over the Blackstone River Viaduct on I-295, the Kingston Road bridge on I-95 or through lane-narrowing work zones.
The heaviest moves need an independent analysis of every structure on the route, and extra-large loads must be applied for several working days ahead.

A value reading "Not confirmed" means we could not verify the figure on an official agency page at review time, so it stays open rather than guessed.
