an additional movement up and down to the signal stick in cars and an additional light in the rear of the car designed in the shape of a U-turn arrow.
Very often when a driver wants to do a U-turn using the normal signal used in cars which is right or left, the driver behind may not be 100% sure whether the driver in front wants to do a u-Turn or simply turn right (or left). My idea is to have two movements for the signal stick for each direction- two up and two down. Eg the first movement down is a normal turning left signal but two movements down means the driver is making a U-turn.This is reflected by an additional light in the shape of a U-Turn arrow in the rear of the car. Similarly two moves up means the first one turning right (with a normal signal of a flashing light in the rear of the car) but the second move up of the signal stick lights the light with the U-Shapr arrow.
Problem this idea/invention addresses:
Drivers behind not knowing what direction drivers in front are going - right/left or a U-Turn.
