Does the towed vehicle have an effect on the field of vision of the driver?
Show the correct answer
Correct answer
C. It has an effect on limiting the field of vision.
Explanation
In the photo, a white van is towing a small delivery van on a rope along a city street. A towed vehicle does limit the driver's field of view - answer C. Answer A is false, and the effect is not limited to U-turns (B).
In the interior mirror, the driver of the towing vehicle mainly sees the bonnet of the towed car, and in the exterior mirrors - its sides; whatever is happening behind the towed vehicle is hidden. So the driver cannot see a motorcyclist who starts to overtake the two vehicles, or a car approaching at high speed. That is why the Road Traffic Act sets conditions for towing: a speed of up to 30 km/h in a built-up area and 60 km/h outside it, dipped headlights switched on, a driver with the required licence in the towed vehicle, a connection that prevents the vehicles from coming apart, a distance between the vehicles of up to 3 m with a rigid connection and 4-6 m with a flexible one, and the towed vehicle marked at the back with a reflective triangle. The Act also requires the vehicle to give the driver a sufficient field of view - when towing, you make up for it by checking the mirrors more often than usual and signalling every manoeuvre earlier, because the other driver has to keep up with you.
