Cross Traffic Alert (sometimes called Rear Cross Traffic Alert) is a system that warns you if a car is approaching from the side when you are backing out of a parking space.
It often works alongside a blind spot warning system, using the same equipment.
If, when you are backing out of a space, the system detects a car approaching from either side it will make a sound or display an alert.
Some vehicles combine this warning with an autonomous braking system that will automatically brake the car if a crash is imminent and the driver doesn’t take action.
Things to be aware of:
- Cross traffic alert systems don’t work in every situation, such as when reversing out of an angled parking space. It also may not spot pedestrians or cyclists so it’s critical that the driver still pays attention in any reversing situation.
