CLAM (Central London Advanced Motorists) is one of over 200 local Groups affiliated to the Institute of Advanced Motorists (IAM).

The IAM is the national body, with over 100,000 members, which promotes and runs the Advanced Driving Test and is an influential voice on road safety.

CLAM and the other local groups are volunteers who support the aims of the IAM and are here to help you prepare for and pass that Test. We do this by providing trained volunteer Observers who will go out with you in your car, assess your driving, and guide you towards being a better driver. For all our members we provide a local forum to meet with other serious drivers, both socially and to share our skills and keep up-to-date on driving matters.

CLAM covers approximately the area of the "020 7" telephone numbers, plus all SW and W postcodes. We welcome commuters who may live further out, and find our evening meetings easier to attend than those in their home area, but cannot always provide them with Observed Drives. If you live outside this area or are interested in the IAM Motorcycle Test, see our Links for neighbouring groups in Outer London.
