This 7.2-mile, 28-minute route takes a north-west loop from Hendon through Montrose Avenue in Burnt Oak, out to Deansbrook Road near Edgware, then returns via Bunn's Lane and Watford Way through Mill Hill. It features 4 roundabouts and 10 traffic signals, with a good balance of residential and A-road driving. Speed limits include 20 mph zones in Burnt Oak, 30 mph on most residential streets, and 50 mph on Watford Way. Compared to Route 850, this one pushes further north-west and has more roundabout practice.

Watch Out For

• Deansbrook Road. Long stretch with 20 mph speed humps; easy to drift over the limit between humps. Stay consistent.
• Montrose Avenue. Residential area with cars parked on both sides, narrowing the road to single-file in places; give way to oncoming traffic when your side is blocked.
• Watford Way southbound. Speed drops from 50 to 30 mph approaching Hendon; miss the sign and you pick up a serious fault.
• Barnfield Road. Tight residential turns where wing mirrors can clip parked vehicles; slow to 15 mph on the corners.

Key Tips

• On Deansbrook Road, treat each speed hump as a reminder to check your speedometer; 20 mph zones are strictly enforced during tests
• At the Watford Way roundabouts, use the two-second rule to judge gaps in traffic from the right before entering
• Through Montrose Avenue, do not force your way past oncoming traffic; pull in behind parked cars and wait if needed
