Blind spot monitoring light
A car with waves or a fault message for the blind spot system.
GENERALLY OK TO PROCEED WITH CAUTION
Book it in when you can · Amber means get it checked
What it means
Blind spot monitors use rear-corner sensors to warn of a vehicle beside you. A warning light means the feature is off or faulted — often a dirty or blocked rear bumper sensor.
Can I drive?
Yes. Rely on your mirrors and a shoulder-check, as you would in any car without the feature, until it clears.
Common causes
A dirty or ice-covered rear bumper (where the sensors live), a trailer or bike rack blocking them, or a sensor fault.
Warning-light symbols and meanings vary by vehicle — always check your owner’s manual. This is general guidance based on what the light indicates, not a physical inspection, and a light on its own never names a failed part.
