Can You Still Drive After the Tire Pressure Warning Light Comes On?

If the tire pressure warning light comes on while driving, it is best to reduce speed, maintain control of the steering wheel, and find a safe place to inspect the tires. Do not continue driving. Whether the tire pressure light disappears afterward or not, it is advisable to visit a nearby repair shop for a follow-up check as a precaution. The reasons for the tire pressure warning light coming on are as follows: 1. Tire repair or inflation without resetting the tire pressure data: Some vehicle models' tire pressure monitoring systems require a self-learning process. After tire repair or inflation, the tire pressure data needs to be reset. Otherwise, even if the tire pressure is normal, the monitoring system will retain the previous fault code, causing the tire pressure light to remain on. Generally, visiting a 4S shop to have the staff use a diagnostic tool to clear the fault code will resolve the issue. If the vehicle has a tire pressure reset button, a manual reset can also be performed. 2. Dead battery in the tire pressure sensor: Tire pressure monitoring sensors can be categorized into external and internal types based on their installation location. External sensors are mounted on the tire's valve stem, while internal sensors are placed inside the tire. Both types of sensors require batteries to operate. External sensor batteries typically last 1-2 years, while internal sensor batteries last 5-8 years. Once the battery is depleted, the tire pressure sensor will stop functioning, triggering the tire pressure warning light even if the tire pressure is normal.
When the tire pressure warning light comes on, I strongly advise you to pull over immediately and check. This light is your vehicle's system alerting you to abnormally low tire pressure, which could indicate a leak, a punctured tire, or a valve stem issue. Continuing to drive poses extremely high risks, significantly increasing the chance of a blowout—especially dangerous at high speeds where tire deformation can lead to loss of control. It also accelerates tire wear, increases fuel consumption, and damages the suspension. Find a safe place to stop, turn on your hazard lights, and inspect the tires for obvious deflation or foreign objects. If you have a spare tire or an air pump, you can perform emergency repairs; otherwise, contact roadside assistance immediately. Ignoring tire pressure issues can turn minor leaks into major problems or even lead to accidents, jeopardizing your family's safety. Make it a habit to check your tire pressure monthly with a gauge to maintain optimal levels.
