It’s that time of year when a lot of people pull their trailer or caravan out of the shed and prepare for a long-distance family outing or camping trip. Whichever the case may be, it’s good to be prepared and catch up on the latest traffic laws regarding the speed limit for caravans and trailers before hitting the road.

For safety reasons and to avoid traffic clogging, the towing speed limit is lower than what applies for the rest of the vehicles on the road. This is additionally influenced by the type of road you are driving on. It usually boils down to three main types of which some have similar rules while others differ slightly.

When you are on the road, you won’t be seeing many signs that directly address the caravan speed limit, and that’s why it’s important that you stay updated on all the rules and regulations.

The undivided highway

The undivided highway, also known as the single lane highway, is the first one we will cover. When driving on this type of road, you have to stick to the far-right side of the road so that the drivers who end up forming a line behind you won’t get clogged for an extended period of time by your slower driving speed.

On most single roads, the speed limit is around 70-60 miles per hour for normal cars, so if you are towing a trailer, caravan or other additional “car luggage”, you’ll have to bump that speed down to 10 mph below the maximum limit. So, in this case, your maximum would be 50mph if the allowed speed limit for cars is 60mph.

Another thing to keep in mind is that you will most likely accumulate a few cars behind you because of the difference in speed. When this happens, it’s perfectly fine to pull over and let them pass by you. In fact, in some states, it is considered a traffic violation if you force the cars behind you to slow down and form a long line.

The Divided Highway

Divided highways are a bit of a different story. They have two sides of the road so other drivers won’t get stuck behind you as often as it happens on a single lane roadway. However, even on this type of road, you will have to drive under the speed limit and it will usually be 10 mph lower than the maximum.

The only difference here is that depending on the state you’re driving in, you will be able to drive either 60 mph or 70 mph while towing your caravan. Keep in mind that even if the law allows you to drive that fast, sometimes it’s safer not to, especially if the road is wet. Another important rule to remember is that you should not drive in the second lane unless the right lane is obstructed in some way.


The Freeway

Freeways are essentially built for travel. They have three or more lanes and they provide room for every traveler that is looking to get to their desired destination, without having to worry about being stuck in long traffic lines. The speed limit for RV’s, caravans and trailers on the motorway may vary from state to state. In Arizona it is 65 mph and triple towing is allowed. However, if you’re traveling cross-country make sure to read up on the laws for the particular states you are going through. We covered what you need to know when driving through Arizona in our other article.

Keeping within the speed limit and staying in your designated lane is important since you have to consider your safety as well as the safety of other drivers on the highway. While Arizona and 11 other states are an exception to this rule, most states prohibit trailer passengers. It is not permitted to drive on the highway if you have somebody sitting in the caravan, so make sure you have enough space in the car for all of your travel buddies before you start your journey.
