On single-carriageways such as the A4226 or A4050, the legal speed limit is 60 mph, but once you get on dual-carriageways like the A48 or A4161, the maximum speed is 70 mph. Note, however, that in residential and commercial areas, you have to reduce your speed to 30 mph; this could drop to as low as 20 mph near schools and hospitals. CCTV cameras are always operational in the city limits, and it is both illegal and dangerous to operate your vehicle under the influence of alcohol or drugs. In cases of emergency, dial 999 for assistance.
