Which Dashboard Warning Lights Should Stop a Road Trip?

Some dashboard lights mean you should stop driving, while others mean you need service soon.

Before a long trip, the most urgent signs are an oil pressure warning, an overheating warning, a brake warning with poor braking, or a flashing Check Engine Light. Do not count on a long drive to make a warning go away.


Which Warning Lights Mean Stop Driving?

A red oil pressure light may mean the engine is not getting enough oil pressure. Pull over safely and shut off the engine. An overheating light or a temperature gauge in the hot zone also calls for a safe stop. Driving farther can turn a small problem into major engine damage.


What About the Brake Warning Light?

A brake warning light may mean the parking brake is on, the brake fluid is low, or the brake system has a fault. Check that the parking brake is fully released. If the light stays on or the pedal feels soft, do not start a road trip. Have the brakes checked first.


Is a Flashing Check Engine Light Serious?

Yes. A flashing Check Engine Light can mean an active engine misfire that may damage the catalytic converter. If the car shakes, loses power, or the light flashes, find a safe place to stop and arrange help. A steady light still needs diagnosis, especially before highway travel.


Can I Travel With a Tire Pressure Light On?

Check tire pressure when the tires are cold and use the pressure listed on the driver door label. A tire that is very low, damaged, or losing air should be checked before driving. If the light keeps coming back, there may be a leak rather than a weather change.


How Can an Inspection Save Money?

A pre-trip inspection can catch a weak battery, worn brakes, tire damage, or a cooling problem before you are far from home. It can also help you decide which repairs need attention now and which can be planned for later.
