When should an ABS warning light turn off?

Explanation: Every vehicle fitted with anti-lock brakes must have a warning light in the cab of the vehicle. The warnings may differ between manufacturers, but on all types the warning light should come on when the ignition is switched on, and turn off when the vehicle reaches a speed of 6 mph (10 km/h). If the light stays on, there may be a fault; you should have the brakes checked before continuing your journey.
