Pedestrians trying to cross the road may also be hidden by such a parked vehicle.

Anyone who accompanies a learner car driver must hold a full EC/EEA licence for the category of vehicle being driven, and they must have held it for at least 3 years. They must also be at least 21 years old. This applies even if they're just helping a friend and no money is exchanged.

Sometimes an insurance company will issue a temporary insurance certificate called a cover note. It gives you the same insurance cover as your certificate, but lasts for a limited period, usually one month.
