Towing speed limits by state

US & Canada

A handful of states set a lower limit for anyone pulling a trailer. Here is each one, read from the law itself, and the states that do not.

Is there a speed limit for towing a trailer?

Only in a few states. Most set their limits by the type of road and apply them to every vehicle, trailer or not. Of the 34 states we have read, 3 set a lower limit for an ordinary car or pickup towing a trailer: California, 55 mph (89 km/h); Virginia, 45 mph (72 km/h) on secondary roads; Washington, 60 mph (97 km/h).

4 more have a lower limit that is tied to a heavy truck rating, not to towing, and 5 let the road authority post a separate limit for a type of vehicle. The other 22 we read treat a towing rig like any other vehicle. 17 states are marked "Not yet verified"; we would rather leave a row blank than copy it from someone else's chart.

Law, not advice. Each row is what the section we cite says, in plain words. The limit that applies is the one where you are driving, so a trip has to follow each state's rule in turn. "Same as other traffic" describes the section we read; it does not promise that nothing else in that state's code mentions trailers.

Towing speed limits by state

Speeds are in miles per hour, the unit the statutes use, with kilometres per hour after them.

Alaska	Same as other traffic	Posted limit	Same limits as any vehicle, unless otherwise posted.	13 AAC 02.275(b)
Arizona	Same as other traffic	Posted limit	Same limits as any vehicle: the rural interstate limit is set for "all types of motor vehicles".	Ariz. Rev. Stat. § 28-702.04(A)
Arkansas	Not yet verified			Not yet read
California	Lower limit when towing	55 mph (89 km/h)	55 mph on every highway for a passenger vehicle, or a pickup or other motortruck, drawing any other vehicle, whatever the posted limit for cars. This catches a car with a utility trailer as well as a truck with a travel trailer, and it applies on freeways posted 65 or 70.	Cal. Veh. Code § 22406(b)
Colorado	Not yet verified		We read § 42-4-1101 only in the 2024 printout, which shows no towing limit, and are holding the row until we read the current consolidation.	Not yet read

Hawaii	Same as other traffic	Posted limit	Whatever county ordinance or state signs set; no separate statutory limit for towing.	Haw. Rev. Stat. § 291C-102(a)
Idaho	Same as other traffic	Posted limit	Same limits as any vehicle. One difference: a vehicle towing another may not use the 15 mph allowance for passing on two-lane roads.	Idaho Code § 49-654
Illinois	Heavy trucks only	Posted limit; lower for heavy trucks	In Cook, DuPage, Kane, Lake, McHenry and Will counties, a truck or other second division vehicle rated to carry a gross weight of 8,001 lb or more is limited to 60 mph on interstates and 55 mph on other roads. Elsewhere the section sets no separate figure. The test is the vehicle's own weight rating, not the trailer, so a heavy-duty pickup can be caught whether or not it is towing.	625 ILCS 5/11-601(e)
Indiana	Not yet verified		Indiana's official code viewer does not serve the section to a static request, so we have not read it yet.	Not yet read

A car towing a trailer follows the general limits. Whether a heavy-duty pickup counts as "more than 1 ton manufacturer's rated capacity" depends on its rating; the section does not say how to read a pickup's ton class.	Mont. Code Ann. § 61-8-312(1)

Vermont	Same as other traffic	Posted limit	Same limits as any vehicle.	23 V.S.A. § 1081(b)
Virginia	Lower limit when towing	45 mph (72 km/h)	45 mph instead of 55 on secondary roads for a vehicle towing a house trailer or a self-propelled vehicle (a car or a motorhome). On interstates, other limited access divided highways, four-lane highways and state primary highways, the section sets no separate towing figure. The lower figure covers a house trailer or a towed vehicle that has its own engine; the section does not name a boat or a utility trailer.	Code of Virginia § 46.2-870
Washington	Lower limit when towing	60 mph (97 km/h)	60 mph maximum for vehicles in combination, which includes any vehicle towing a trailer.

The states people ask about most

Towing speed limit in California

55 mph. Cal. Veh. Code § 22406(b) limits a passenger vehicle or bus drawing any other vehicle to 55 mph on every highway, and subsection (a) does the same for a pickup or other motortruck drawing a trailer. It does not matter what the trailer is or what the freeway is posted at: a car with a small utility trailer on a freeway posted 65 or 70 is still held to 55.

Towing speed limit in Arizona

The posted limit. Ariz. Rev. Stat. § 28-702.04(A) sets the rural interstate limit for "all types of motor vehicles", 65 mph, which the director may raise to 75. We found no separate statutory figure for towing.

Towing speed limit in Nevada

The posted limit, unless a separate one is posted for trailers. Nev. Rev. Stat. § 484B.613(2) lets the Department of Transportation set a lower limit "for trucks, overweight and oversized vehicles, trailers drawn by motor vehicles and buses". Nevada's absolute cap of 80 mph applies to every vehicle.

Towing speed limit in Utah

The posted limit, unless a separate one is posted for your type of vehicle. Utah Code § 41-6a-602(2) lets UDOT set different limits by type of vehicle; the statute itself has no towing number, and 55 mph is the default where nothing is posted.

Towing speed limit in Washington

60 mph. Rev. Code Wash. § 46.61.410(2) and (3) caps "vehicles in combination" at 60 mph and says a "Trucks" speed sign covers all vehicles in combination, so a lower posted truck limit applies to a car or pickup with a trailer as well.

Towing speed limits in Canada

None of the provinces we have read sets a lower number for a vehicle towing a trailer: the posted limit applies. Speeds are in kilometres per hour, the unit the law uses.

How fast should you tow?

Guidance, not law. The law sets a ceiling. These are the things that set a lower one for your own rig.

Trailer tires: the sidewall carries a speed rating, and many trailer tires are rated below highway speeds. The trailer tire page covers how to read it.
Sway: a trailer that is light on the tongue gets less stable as speed rises. Check the tongue weight with the tongue weight calculator before you blame the wind.
Stopping: a heavier rig needs more distance. Make sure the trailer has brakes where the law asks for them; the trailer brake rules are by state and province.

In Washington, yes: Rev. Code Wash. § 46.61.410(2) and (3) says the word "trucks" on speed signs means vehicles over 10,000 lb gross and all vehicles in combination, and a car with a trailer is a combination. Elsewhere it depends on how that state defines the vehicles the sign covers. Where a state lets its transportation department post limits by type of vehicle (Nevada, Utah, Delaware, North Dakota, South Dakota), a sign for trailers or trucks may apply to your rig.

Can I go faster than 55 mph with a trailer in California?

No. Cal. Veh. Code § 22406(b) sets 55 mph for a passenger vehicle drawing any other vehicle, and a higher posted freeway limit does not change that.

Is it safe to tow at the posted speed limit?

The posted limit is the most the law allows, not a target. Many of the sections we read, Florida's and Idaho's among them, also forbid driving faster than is reasonable for the conditions, and a loaded trailer stops longer and sways more. Trailer tires also carry their own speed rating on the sidewall, which can be lower than the road's limit.
