Reversing a trailer is one of those skills that feels impossible… right up until it clicks. The trick is slow speed, small steering inputs, and constant observation. This guide explains how to reverse a trailer step by step (reversing to the left, which is generally easier), plus key notes about auto-reverse brakes.
Before You Start: Quick Reversing Rules
Go slow. Reversing fast is how jack-knifes happen.
Use your mirrors, and don’t be shy about stopping to check.
If you’re unsure which way the wheels are pointing, lean out and look.
Older trailers (often pre-1989) may have a manual reverse brake lever to stop brakes applying when reversing.
Trailers built after 31 March 1989 typically have auto-reverse brakes, so they can reverse without the brakes locking on.
Step-by-Step: Reverse a Trailer to the Left
1) Start Straight and Give Yourself Space
Set the vehicle and trailer as straight as possible, about one trailer length away from where you want to end up. You need room to swing the tow vehicle around — tight starts make everything harder.
2) Reverse Slowly and Add Steering Gradually
Watching the trailer through the driver’s window (or mirror), reverse slowly and begin steering to the right to send the trailer left.
Key tip: It’s easier to add more steering than to correct too much.
3) Straighten Early to Avoid Jack-Knifing
As soon as the trailer starts turning, begin to straighten the steering while still reversing.
If you leave it too late, you risk a jack-knife (the trailer reaches too sharp an angle to the tow car). This can also be a problem for vehicles with long rear overhangs.
4) “Follow” the Trailer With the Tow Vehicle
Once the trailer is turning into position, start steering the other way (still reversing) to bring the tow vehicle’s nose around so the car follows the trailer.
Keep watching the trailer path — you’re guiding the trailer, not the car.
5) Reverse Straight Using Mirrors (Micro-Corrections Only)
When you’re lined up, reverse in a straight line using mirrors.
A simple rule:
If more of the trailer appears in one mirror, steer gently towards that mirror to bring it back.
These corrections should be small and smooth.
6) Don’t Be Afraid to Pull Forward
If it starts going out of line, it’s often faster (and safer) to pull forward and reset than to fight it in reverse.
On tight turns or if it jack-knifes, pulling forward may be your only option.
Quick “Do This / Don’t Do This”
✅ Do
Move slowly
Use tiny steering inputs
Stop and check when unsure
Pull forward to correct
❌ Don’t
Try to “save it” with huge steering swings
Reverse quickly
Keep forcing it when it’s folding up
