What should you do when the wheels of your trailer begin to skid?
Correct answer: Stop applying the brakes.
Answer options
- APull the trailer hand brake to straighten the rig
- BStop applying the brakes Correct
- CPump the brakes rapidly
Why
A trailer skid usually starts when the trailer wheels lock, so letting off the brakes allows them to roll and grip the road again; the trailer will then follow the tractor and straighten out. Using the trailer hand brake makes things worse, because braking the trailer wheels is what caused the skid.
