Rad Alert / Arrow turn signal

When people is driving a car, blind spots are the areas of the road that cannot be seen while looking forward or through either the rear-view or side mirrors. The most common are the rear quarter blind spots, areas towards the rear of the vehicle on both sides. Vehicles in the adjacent lanes of the road that fall into these blind spots may not be visible using only the car's mirrors.
If the car doesn’t be equipped with side-mounted turn signal, other motorcycle drivers who can’t see the car’s front blinker will easily cause car crashes when turning or changing lanes.
