Route 1810 runs 6.8 miles in about 26 minutes as a single stage across Bernards Heath and Marshalswick, with limits between 20 and 40 mph. Nothing on it climbs above 40 mph, so it stays in built-up traffic, yet its four roundabouts put it among the busier routes for roundabout work at this St Albans office.

Watch Out For

• Seven right turns against three lefts, most of them emerging from residential roads onto busier carriageways.
• Hatfield Road near the start, where parked cars narrow the running lane.
• Nine sets of traffic signals, several of them close together on the city centre section.

Route Features

• Long residential stretches along Sandridge Road and Marshalswick Lane.
• Four roundabouts, each needing you to give way to the right and signal left on exit.

Test Manoeuvres

• Pull up on the left close to the test centre.

Key Tips

• 20 mph zones sit right beside 30 and 40 mph roads here, so confirm the limit after each turn.
• Quiet estate roads still carry parked cars and driveways, so keep observation active between the roundabouts.
