Once, while walking to work, I saw a car turning right and carried a message saying "Turn right, please be careful"; I personally think this reminder is very good. Nowadays, many school buses and buses usually install this reminder, but it is rare for specialized vehicles to install it.

However, recently Wuhan has been promoting the installation of this right turn indicator on trucks to reduce accidents. Due to the large size and length of large vehicles, the turning paths of the front and rear wheels are not consistent when turning right, resulting in an inner wheel difference of 1-2 meters. This area is also a visual blind spot for truck drivers, and if pedestrians and vehicles are too close to the blind spot, traffic accidents are very likely to occur.

Right turn trajectory

According to the Wuhan traffic police department, in order to reduce the risk of heavy truck accidents, the Wuhan traffic management department has cooperated with PICC. We will gradually promote the installation of right turn reminders on trucks. When trucks turn right, they will emit a warning sound "Vehicle turning right, please pay attention!" to remind pedestrians and vehicles located on the right side of the vehicle to give way.
