Road Traffic Acts

These are primary legislative documents that govern all aspects of road use, including vehicle standards, driver behaviour, and road infrastructure.

The Road Traffic Acts in Ireland and the UK provide the legal framework for road safety and management. They cover a vast array of topics, from speed limits and driving offences to vehicle construction and use, and the powers of road authorities. While not a technical design standard, they underpin the legal requirements for all road engineering and design decisions, ensuring that infrastructure facilitates safe and lawful road use.
