Visibility<br />
To manoeuvre safely the driver needs to be able to<br />
see all around the vehicle or to be automatically<br />
warned if there is a person or object in the danger<br />
area. Vehicles should be designed to provide<br />
adequate visibility <strong>and</strong> be fitted with windows<br />
(including side windows), mirrors, closed circuit TV<br />
<strong>and</strong> sensing equipment as appropriate.<br />
Many vehicles have substantial blind spots not only<br />
immediately behind the vehicle, but also alongside<br />
<strong>and</strong> immediately in front of it. Accidents occur when<br />
vehicles move off or turn while a pedestrian or vehicle<br />
is passing in blind spots. How to avoid these blind<br />
spots is illustrated in figures 21 <strong>and</strong> 22 below.<br />
