If you require glasses to drive then you will need to carry a spare set in the vehicle at all times.
You will need two approved triangles in the vehicle ( only one if the vehicle is UK registered ) along with an approved light reflecting jacked. Should you break down on a main public highway or motorway you are not allowed to leave the vehicle unless you are wearing a jacket, the triangles can then be placed at a distance of around 30 meters behind the vehicle to warn oncoming traffic.
You are not allowed to use radar speed checking devices which can be part of or separate to GPS systems, the fines are heavy if you are caught using this type of device.
On the spot fines can be issued although you are in your right to request an official receipt from the officer collecting the fine.
