What may limit your field of vision when you ride a motorcycle?
Show the correct answer
Correct answer
A. Incorrectly-fitted glasses and helmet.
Explanation
In the photo a motorcyclist in a full-face helmet with the visor closed is waiting in front of a pedestrian crossing in town. The field of view of a motorcycle rider can be limited by badly fitted glasses and helmet - answer A.
The Road Traffic Act requires the driver to see the road and to have control of the vehicle, and a wide field of view is a condition for this. A helmet that is too small, badly positioned or with a narrow visor opening cuts off the view at the sides - and that is exactly where cars come from at a junction; a scratched, misted-up or tinted visor makes visibility worse in rain and at dusk. Glasses with narrow lenses or with wide arms pressed in by the helmet do the same, and the wrong correction blurs signs. The motorcycle itself (answer B) does not limit the rider's vision, and overalls (answer C) protect the body but do not affect sight, unless the collar prevents you from turning your head. Before riding you check that the visor is clean and that the helmet does not press on your glasses; at night you ride with a clear visor.
