Route 1819 runs 6.3 miles in about 27 minutes as a single stage, linking Cottonmill, Sopwell, The Camp, London Colney and Cotlandswick. Limits run from 20 to 70 mph and it carries 12 sets of traffic signals, more than several longer routes at this St Albans office manage, with seven right turns against three lefts.

Watch Out For

• Marked cycle lanes on the southern section, which you must not cut across when turning.
• A school zone with a reduced limit and children near the kerb.
• The 70 mph stretch that drops back to 40 mph on the approach to the built up area.

Route Features

• Residential roads such as Cottonmill Lane before the faster run past Cell Barnes Lane.
• One roundabout, with priority to the right and a left signal on exit.

Test Manoeuvres

• Pull up on the left near the test centre.

Key Tips

• Check the nearside mirror before every left turn because of the cycle lanes.
• Limit changes are frequent here, so read the signs rather than following the car ahead.
