Rule 40 - The Highway Code

When moving off the pavement onto the road, you should take special care. Before moving off, always look round and make sure it’s safe to join the traffic. Always try to use dropped kerbs when moving off the pavement, even if this means travelling further to locate one. If you have to climb or descend a kerb, always approach it at right angles and don’t try to negotiate a kerb higher than the vehicle manufacturer’s recommendations.
