PURPOSE: An automatic sensor brake ramp lights a brake ramp when a foot gets close to a brake pedal within 5 centimeters, thereby reducing a danger of a crash with a car running behind. CONSTITUTION: A sensor(4) is mounted on a brake pedal(2). A brake ramp is turned on when a foot gets close to the brake pedal(2) within 5 centimeters. A driver of a car running behind has time to sense a speed reduction of a preceding vehicle and avoids a crash accident with the preceding vehicle. Therefore, an automatic sensor brake ramp reduces accidents due to a rapid braking by alarming the rear drivers that the front car is starting to brake.
