A sudden downpour could make it tough to see when you’re driving. But heavy rain can also obscure the “vision” of your car’s security system, probably placing you in peril, new testing finds.

According to an evaluation by AAA, reasonable to heavy rain can scale back car security system efficiency considerably. In closed-course testing that used simulated rainfall, AAA discovered that:

  • Test autos with computerized emergency braking collided with a stopped car 33% of the time when touring at 35 mph
  • Test autos with lane-keeping help expertise departed from their lane 69% of the time

AAA notes that car security techniques typically are evaluated in perfect working circumstances as an alternative of utilizing the real-world circumstances that drivers generally face.

In a press launch, Greg Brannon, AAA’s director of automotive engineering and trade relations, says:

“Vehicle safety systems rely on sensors and cameras to see road markings, other cars, pedestrians and roadway obstacles. So naturally, they are more vulnerable to environmental factors like rain.”

In further testing, AAA discovered {that a} simulated soiled windshield lined with a focus of bugs, dust and water didn’t negatively have an effect on general safety-system efficiency.

However, AAA notes {that a} soiled windshield can nonetheless have an effect on safety-system cameras, and the group urges drivers to maintain windshields clear.

This just isn’t the primary time that AAA has uncovered flaws in car security techniques. Earlier testing discovered that autos:

  • Struggle to remain of their lanes in reasonable site visitors, on curved roadways and close to busy intersections
  • Fail to cease for pedestrians in lots of conditions, together with when individuals cross in entrance of a car or a toddler darts out between two parked autos
  • Hit disabled autos or veer too near different autos or guardrails

AAA says such failures underscore the necessity for added fine-tuning of security techniques. For now, AAA recommends that drivers take steps reminiscent of:

  • Keeping windshields clear
  • Avoiding laborious breaking and sharp turning
  • Remaining 5 to 6 seconds behind the car forward
  • Easing off the accelerator — reasonably than hitting the brakes — when the car begins to hydroplane
