There is a 20mph speed limit along Swansea High Street and other districts within thriving commercial and institutional areas, but outside these precincts, the national speed limit of 30mph should be applied. On primary roads like the A4067 and A483, speeds of between 40mph and 50mph are allowed and if you make it out to the M4 the limit increases to 70mph. CCTV and traffic cameras are always in use along busy highways and at junctions, so drive with care and observe the stated limits whenever possible. Search car hire on KAYAK
