Look round for a final check and then move off only when it is safe.
Always follow these rules for using the road and general guidelines before you move off. Motorists should continue using them even when they are on the move in their vehicle.
Rule 160: Once your vehicle starts moving you should keep it to the left side of the road. This rule applies until or unless road signs and markings direct you to take a different action.
Note: There are some exceptions to Highway Code rule 160. They include times when you want to overtake another vehicle or turn right at a junction. Maneuvering passed parked vehicles or pedestrians in the roadway is another exception.
While moving along and using the road you should also:
Keep well to the left side of the road while you are maneuvering right-hand bends.
Keep left to improve your view of the road. It also helps to reduce the risk of colliding with traffic approaching from the opposite direction.
Drive with both hands on the steering wheel whenever possible. That drivers remain in full control of their vehicle at all times. You can use driver assistance systems while driving. But, you must use any such system according to the manufacturer's instructions.
Be aware of other motorists using the road. This rule applies most to cycles and motorcycles. Bike riders may be filtering through the traffic more often than cars and trucks.
Be aware that smaller road users are more difficult to see than larger vehicles. Cycle riders are particularly vulnerable.
Give plenty of room to cyclists and motorcyclists especially if you are driving a long vehicle or towing a trailer.
