Route 1818 covers 6.0 miles in about 25 minutes as a single stage through Marshalswick and Bernards Heath, with limits between 20 and 40 mph. It has no roundabouts and just six sets of traffic signals, among the lightest at this St Albans office, so almost all of the assessment falls on its 15 turns through residential streets.

Watch Out For

• Nine right turns, most of them emerging from estate roads onto busier through routes.
• Sandpit Lane and Sandridge Road, where traffic runs faster than the side streets feeding them.
• Parked cars narrowing residential roads such as Beech Road.

Route Features

• A compact suburban loop reaching The Ridgeway before returning to the city.
• Limits stay between 20 and 40 mph throughout, with no dual carriageway section.

Test Manoeuvres

• Pull up on the left near the test centre.

Key Tips

• Fifteen turns across 6.0 miles means instructions come quickly, so begin observations early.
• Confirm the limit each time you leave a 20 mph residential street.
