You’re crawling in heavy traffic, your phone lights up on the passenger seat and you instinctively reach for it. Many drivers still aren’t clear when that moment crosses the line from bad idea to offence. In broad terms, mobile phone use at the wheel means any interaction with a phone while you’re in control of a moving or ready-to-move vehicle.

Handheld: almost always illegal

The basic rule is blunt: if you are holding a phone while driving, expect it to be treated as illegal. That includes texting, scrolling music, checking maps, taking photos or videos, balancing it on your lap or between your legs, or simply having it in your hand on loudspeaker.

It does not matter if you believe you are in control or “only looking for a second”. Police and courts tend to treat any handheld use as a high-risk distraction, and penalties usually involve a noticeable fine plus several penalty points. For new drivers in their first couple of years on the road, those points can be enough to trigger licence revocation, and enforcement can come from marked or unmarked vehicles, elevated viewpoints and roadside cameras.

Stopped but still driving

This is where many otherwise careful drivers get caught. If you are stopped in a live lane with the engine running – at lights, in a queue, at a junction – you are still normally considered to be driving, even if the car is not moving at that moment.

In those situations, handheld phone use is usually treated in the same way as on the open road and can lead to similar penalties. The safer approach is simple: if traffic could move and you would be expected to move with it, keep your hands off the phone until you are properly parked with the engine off.

Hands-free and in-car screens

Hands-free use is generally allowed if you do it properly. That means the phone is secured in a stable cradle where it does not block your view, and you control it mainly with voice commands or steering wheel buttons rather than touching the handset.

Using your phone as a sat-nav is also usually permitted, provided you set the route before moving off and do not pick the phone up while driving. Many cars now have touchscreens that mirror apps from your phone, but tapping through menus for playlists or messages still takes your eyes off the road. If officers or cameras see you clearly distracted, weaving in your lane, failing to notice hazards or not moving off when you should, action is possible under careless or dangerous driving laws even if the setup is technically hands-free.

Checklist

  • Use a solid phone cradle at roughly eye level and never drive with the phone on your lap or loose on the seat.
  • Set routes, playlists and podcasts before you move off so you are not tempted to fiddle with the phone in traffic.
  • Activate driving or “do not disturb” modes to cut non-essential notifications while you are on the road.
  • If you need to take a call or read a message, pull over somewhere legal and safe, switch the engine off and only then pick up the phone.
  • Keep any taps on built-in or mirrored screens brief and infrequent; if it needs more than a quick press, deal with it when you are stopped.

Treat any moving or ready-to-move car as “no phone time”, and make full use of cradles, voice control and safe stopping places. That habit cuts the risk of penalties and gives you vital reaction time if something suddenly changes ahead.
