In addition to honking their is safety involved here.
- In addition the authorities have to ensure that the side mirrors of these vehicles are in working conditions. If the side mirrors are not in working conditions; they do not know who is in parallel lanes. And when they change the lane they are hazard to other vehicles.
- Also their tail lamps and brake lamps have to be checked. Driving behind such vehicles in dangerous when brake and tail lamps are not working especially in the evening. Worst when such vehicles are parked without working tail lamps. Hence driving in the evening becomes hazardous more so on Mumbai Pune Expressway.
