Difficulty: EasySpeed Limits

A driver is operating a standard solo car across different UK road environments where default national speed limits apply. Match each road type to its legal maximum speed limit.

  • Built-up street with continuous street lighting and no posted speed signs30 mph
  • Single carriageway road displaying the national speed limit sign60 mph
  • Dual carriageway road displaying the national speed limit sign70 mph

Answer

Built-up street with street lighting pairs with 30 mph; Single carriageway pairs with 60 mph; Dual carriageway pairs with 70 mph.
According to the UK Highway Code, a solo car is limited to 30 mph on lit urban roads, 60 mph on single carriageways, and 70 mph on dual carriageways when the national speed limit applies.

Step-by-Step Solution

1
Identify the rule for built-up roads with street lighting
The presence of street lights without specific repeater signs establishes a default 30 mph limit.
Street lighting indicates an urban or built-up area where pedestrian traffic requires lower vehicle speeds.
2
Identify the national speed limit for a solo car on a single carriageway
A standard car has a maximum permitted limit of 60 mph on an unrestricted single carriageway.
Single carriageways lack a physical central barrier, so the national limit is set at 60 mph for safety.
3
Identify the national speed limit for a solo car on a dual carriageway
A standard car has a maximum permitted limit of 70 mph on an unrestricted dual carriageway.
Dual carriageways feature opposing traffic separated by a central reservation, permitting a 70 mph limit.
