We've seen many times when we're on the freezing road in winter and we're forced to bump into the brakes so long that we're standing in front of us, so we've seen a crash and lost people and cars from multiple collisions. This has been very large;The present invention attaches the detent (6) under the vehicle in order to shorten the braking distance, and in the case of the driver, the driver depresses the brake and pulls the handle (41) forward with his left hand (5) at the end of the detent (5). Since it is laid on the ground and presses and mows the ground with the expansion force of the spring (9), the slipping distance is shortened, so even if it stops just before the collision, no accident will occur.;Detent (6) Coil Spring (9) Operating Rod (15)
