Difficulty: EasySpeed Limits on Motorways

Match each motorway driving situation or signal with its corresponding legal speed limit rule or status.

  • Solo car driving on an unrestricted motorway70 mph national speed limit
  • Car towing a trailer driving on an unrestricted motorway60 mph reduced national speed limit
  • Overhead gantry showing a speed limit number inside a red ringMandatory variable speed limit that is legally enforceable
  • Overhead gantry showing a speed limit number with flashing amber lightsAdvisory speed limit recommended for prevailing conditions

Answer

Solo car on unrestricted motorway matches 70 mph; Car towing trailer matches 60 mph; Red ring gantry sign matches mandatory variable speed limit; Flashing amber lights match advisory speed limit.
Under the UK Highway Code, the national speed limit on an unrestricted motorway is 70 mph for solo cars, but reduces to 60 mph when towing a trailer or caravan. On smart motorways and variable limit sections, speeds displayed inside a red circle are legally mandatory, whereas flashing amber lights provide advisory speed recommendations.

Step-by-Step Solution

1
Determine the statutory national speed limit for cars based on whether they are towing.
Solo cars are subject to 70 mph, while cars towing a trailer or caravan are subject to 60 mph.
The UK Highway Code specifies a 10 mph lower statutory maximum for towing vehicles on motorways to ensure vehicle stability.
2
Distinguish between the legal status of red circle signs versus amber flashing matrix signals.
Red circle signs are mandatory; amber flashing signals are advisory.
Red rings convey legal orders and mandatory limits, whereas flashing amber lights warn of temporary hazards or recommend safe speeds.
3
Pair each situation on the left with its corresponding rule on the right.
All four items are correctly matched to their respective limits and legal definitions.
Completes the matching criteria accurately according to UK driving regulations.
