what does it normally mean when driving on a road with street lights?
You MUST NOT exceed the maximum speed limits for the road and for your vehicle (see the speed limits table). The presence of street lights generally means that there is a 30 mph (48 km/h) speed limit unless otherwise specified.ou MUST NOT exceed the maximum speed limits for the road and for your vehicle (see the speed limits table).
