Pull Over Now — Urgency 5/5Do not drive with a flashing check engine light. Pull over safely, turn off the engine, and arrange a tow.

This is general guidance. Your situation may differ — when in doubt, don’t drive.
What does this mean?
A flashing check engine light is very different from a steady one. This means something serious is happening right now — usually an engine misfire that could damage your catalytic converter or engine if you keep driving. Think of it as your car shouting rather than whispering.
What should I do right now?
Slow down immediately and pull over as soon as it is safe to do so. Turn off the engine and call for roadside assistance or a tow to your mechanic. Do not try to drive to the garage yourself — every minute of driving could cause expensive damage.
