UK law is clear: it is illegal to hold or use a mobile phone while driving — even when stopped at traffic lights or in traffic. Since the 2022 updates, this applies to any use of a hand-held device, not just calls or texts. Drivers may only use devices hands-free, and must remain fully in control of the vehicle at all times. For fleet operators, this makes secure, properly fitted mounting solutions essential — helping reduce risk, support hands-free compliance, and keep drivers focused on the road.
