Speed limits when towing

Towing speed limits Towing Speed limits my nrma

Last updated: 09 August 2024

Do you ever tow a caravan, trailer, or boat? Obviously, you’ll need a vehicle that’s up to the job, but it might surprise you to learn that many manufacturers impose reduced speed limits for towing – either across the board or when the weight of the trailer exceeds a certain limit.

It can get a bit confusing, so here’s a quick overview of the various limits to get you up to speed.

First, if you’re looking to buy a vehicle and using it to tow, be sure to check the handbook, towing tips, warnings, and restrictions set by the manufacturer on that specific model. While some allow you to travel at 110km/h, others have towing speed limits as low as 80km/h, so it’s important to choose a vehicle that meets your needs.

Australian states towing limits

Different states may have different open road speed limits when towing up to 4500kg. For instance, Western Australia has a 100km/h maximum for all trailers, and Tasmania’s maximum speed limit on gravel roads is 80km/h for everyone. As you can see, it varies quite a bit, so it's very important to read ahead before hitting the road. Most states use towing speed limit signs, so keep an eye out while travelling.

Subaru towing limits

All Subaru vehicles are restricted to 80km/h when towing. As outlined in all Subaru manuals, “Never exceed 80 km/h (50mph) or the legal speed limit, whichever is lower. Exceeding the speed limit could cause loss of vehicle stability and/or could lead to an accident.”

The Subaru Outback’s handbook further warns drivers of changes to steering, stability and braking performances when towing. “You should never drive at excessive speed but always use extra caution when towing a trailer.”

Reassuringly, if a Subaru driver exceeds the 80km/hr towing recommendation, but does not exceed the legal speed limit, it won’t void the warranty or affect the vehicle’s insurance in any way.

Ford towing limits

Ford uses a sliding scale of restrictions for Territory and Falcon models. The speed limit is 80km/h when towing maximum loads, which range from 1200kg for a manual transmission Falcon to 2700kg for an AWD Territory.

To travel at 100km/h, Australian Fords should be towing no more than 1200kg. However, engineers stress that owners should check the towing advice specific to the vehicle model, load conditions and trailer type.

Holden, Hyundai, Mazda, Isuzu towing limits

There are no speed restrictions imposed by these manufacturers when towing with their vehicles. However, all recommend that drivers abide by road limits. As a Holden spokesman clarified to the NRMA, “it goes without saying that we would advise drivers to obey local speed limits.”

Mitsubishi towing limits

While Mitsubishi doesn’t impose an 80km/h maximum the manufacturer does offer a comprehensive towing guide. It recommends reducing open road cruising speeds when towing for better control and less mechanical stress.

Mitsubishi explains that reducing speed also helps to maximise fuel economy, noting that “speeds of 80 to 90 km/h are recommended when towing caravans or trailers that create an increase in wind resistance. Higher speeds will significantly increase fuel usage and engine operating temperature.”

Toyota towing limits

The only towing speed restriction set by Toyota is a 100km/h limit on the Prado wagon.

A matter of safety and insurance

Manufacturers’ towing limits are mostly set for better safety and vehicle durability. But besides that, it’s important to realise that exceeding restrictions could also affect any insurance claims or even become a legal liability in the event of a serious accident.

So, take the time to get to know the limits and recommendations that apply to your vehicle, and hit the open road equipped with the knowledge you need to have a safe and happy journey.
