Essential Car Trailer Safety Checks Before Every Trip

Whether you're heading to a race meet, moving a project car, or transporting vehicles for work, your trailer plays a critical role in getting your cargo from A to B safely. But just like your vehicle, your trailer needs regular checks to ensure it's roadworthy and ready for the journey ahead. Before you hit the road, take a few minutes to run through these essential car trailer safety checks. They could save you from costly repairs, dangerous situations—or worse. 

Inspect Tyres and Tyre Pressure 

One of the most common causes of trailer accidents is tyre failure. Check all tyres for visible signs of damage, such as cracks, bulges, or worn tread. Don’t forget to check the spare as well. Use a pressure gauge to ensure the tyres are inflated to the manufacturer’s recommended PSI. Under- or over-inflated tyres can affect handling and increase the risk of blowouts. 

Check the Wheel Bearings 

Wheel bearings allow the wheels to spin freely and are essential for safe towing. Listen for unusual noises when you spin each wheel, and check for any signs of excess play or resistance. If your trailer hasn’t been used in a while, it’s a good idea to repack the bearings with grease or replace them if necessary. 

Test the Brakes and Brake Controller 

If your trailer is fitted with electric brakes, ensure the brake controller in your vehicle is properly connected and functioning. Test the trailer brakes before setting off to confirm they respond when the controller is activated. If your trailer uses mechanical override brakes, inspect the coupling and cables for wear or damage. 

Examine Lights and Wiring 

All indicators, brake lights, tail lights, and reflectors must be clean, visible, and in working order. Plug the trailer into your tow vehicle and check each light function—left and right indicators, brake lights, and running lights. Inspect the wiring harness and connections for corrosion or fraying, as faulty wiring is a common cause of lighting failures. 

Secure the Load Properly 

A well-secured vehicle or cargo is critical for safe transport. Double-check that your car is correctly positioned and tied down with rated straps or chains. Ensure there’s no risk of movement while driving, and that ramps, winches, or other accessories are properly stowed. 

Inspect the Coupling and Safety Chains 

The trailer coupling must be correctly hitched to your tow vehicle and locked in place. Safety chains should be crossed under the coupling and securely fastened. These chains act as a backup if the coupling fails and help maintain control in an emergency. 

Review Registration and Load Limits 

Before every trip, confirm that your trailer’s registration is up to date and visible. Also, know your trailer’s ATM (Aggregate Trailer Mass) and make sure you’re not exceeding it. Overloading a trailer compromises braking performance, handling, and tyre integrity. 

Regular safety checks aren't just a legal requirement—they’re a smart way to protect your investment and everyone on the road.
