Question 1251 · Truck theory test
What effect do the hazard warning lights have on the brake lights?
Pick an answer to test yourself.
Correct answer
They have no effect.
Official explanation

Use the hazard warning lights to warn other road users of a danger ahead when your vehicle is broken down and causing an obstruction or when you need to slow down sharply on a motorway.
