Restricted view: revision notes
Large vehicles have big blind spots, especially close to the front of the cab and down the nearside. Cyclists and pedestrians can disappear from view completely.
- Mirrors: adjust them before every journey and use them throughout, especially your nearside mirror when turning left.
- Front blind spot: check the area directly in front before moving off; children and pedestrians can be hidden by a high cab.
- Advanced stop lines: stop far enough back to see the whole cycle area.
- Lost from view: if a cyclist disappears from your mirror, assume they're alongside you.
- Reversing: if you can't see clearly, get someone to guide you. Cameras and sensors help but don't replace looking.
- Weather: clear all snow and ice from windows, mirrors and lights; in fog, be able to stop within the distance you can see.
Bus drivers should also check the stairs and doors before moving off, and make sure passengers aren't blocking the mirrors.
