CTA - Cross Traffic Alert

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.

• 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.
