Does leaving the hazard lights on drain your car battery?

Yes, leaving your hazard lights on can drain your car battery, especially if the engine is off. Hazard lights use electrical power from the battery to operate, and if left on for an extended period, they can deplete the battery's charge. If the battery is already weak or old, the risk of it being drained increases significantly. To avoid this, it's best to turn off the hazard lights when they're no longer needed.
