Rule 67 - The Highway Code

You should

• look all around to make sure it is safe before moving away from the kerb, when pulling out to overtake or to pass stationary vehicles, or when turning at junctions or stopping
• watch out for obstructions in the road, such as drains, service covers and potholes, positioning yourself so you can move to the left (as well as to the right) to avoid them safely
• take care when passing parked vehicles, leaving enough room (a door’s width or 1 metre) to avoid being hit if a car door is opened, and watch out for pedestrians stepping into your path
• be aware of traffic coming up behind you, including other cyclists, and give a clear signal to show other road users what you intend to do see ‘Signals to other road users’)
• take extra care near road humps, narrowings and other traffic calming features
• when cycling on the road, only pass to the left of large vehicles when they are stationary or slow moving and you should proceed with caution as the driver may not be able to see you. Be particularly careful on the approach to junctions or where a large vehicle could change lanes to the left.
