What does a circle with an exclamation mark on a car indicate?

A circle with an exclamation mark appearing on a car refers to the brake warning light, also known as the handbrake warning light. The reasons why the handbrake warning light on the car dashboard illuminates are: 1. The handbrake is not released or not fully released; 2. Severe wear of the brake friction pads; 3. Low brake fluid level; 4. Insufficient or no brake fluid; 5. Damaged connector of the brake fluid sensor. Common indicator lights on the car dashboard include the engine oil indicator, water temperature indicator, handbrake indicator, battery indicator, ABS indicator, seat belt indicator, engine operation status indicator, brake indicator, refueling indicator, airbag indicator, etc.
Every time I see that warning light with an exclamation mark inside a circle on the dashboard, I feel a bit nervous because it means the tire pressure might be too low. I've experienced it myself when driving—the light came on before getting on the highway, and it turned out the front tire had a slow leak. This light is called the TPMS warning light, which stands for Tire Pressure Monitoring System. If it lights up, don't ignore it. Find a safe place to pull over as soon as possible and check the pressure of all tires. It's handy to keep a tire pressure gauge in the car, and gas station air pumps work fine too. Don't wait for it to fix itself—low pressure increases tire wear and can even lead to loss of control. Safety first—I recommend checking tire pressure monthly, especially when temperatures fluctuate significantly.
As a veteran driver with over a decade of experience, when that circle-with-exclamation-point light comes on, I immediately know there's a tire pressure issue. This is a standard warning system in modern vehicles, alerting you to low tire pressure. The causes can vary – maybe a nail puncture causing air leakage or temperature drops reducing pressure. In such cases, the car becomes unstable to drive and fuel consumption increases. My usual approach is to pull over at the nearest safe spot and use the portable pressure gauge to check all tires against the normal range (typically indicated on a label by the door). If pressures are normal but the light persists, it might be a sensor malfunction requiring garage inspection. Remember, abnormal tire pressure increases blowout risks – early intervention saves both hassle and money.
