Congestion while Driving
Delays & Diversions
Always carry a map or have a reliable navigation app.
If you’re diverted, you’ll be able to find an alternative route safely.
If you use a sat nav:
-
Don’t rely on it blindly — use your own judgement.
-
Pull over safely if you need to recheck directions.
-
Never let the screen distract you from the road.
Mobile Phones
Mobile phones are invaluable in emergencies, but it’s illegal to use one while driving — even when stopped in traffic.
If you’re alone, stop in a safe location before making a call.
On motorways, always leave the motorway before using your phone.
Hazard Perception
Look well ahead and anticipate how traffic is moving.
If you see vehicles slowing, ease off the accelerator early rather than braking hard at the last moment.
Smooth, anticipatory driving helps reduce fuel use and prevents congestion.
Maintaining a Constant Speed
When road conditions are good and visibility is clear, maintain a steady cruising speed within the limit.
Use cruise control if fitted and conditions are safe.
Keep a safe following distance, especially in wet, icy, or foggy weather.
Only drive as fast as you can safely stop within the distance you can see to be clear.
Variable speed limits shown on motorway gantries are mandatory and designed to keep traffic flowing smoothly.
Maintaining a consistent speed generally improves journey times and reduces fuel use.
Lane Discipline
Keep to the left-hand lane on dual carriageways and motorways unless overtaking.
If overtaking several slower vehicles, stay in the overtaking lane only as long as necessary, then return left.
Avoid “lane hogging” — especially in the middle lane — as it blocks faster traffic and reduces road efficiency.
You must not drive on the hard shoulder unless directed by signs or during authorised roadworks.
Using Road Signs & Signals
Watch for overhead motorway signs and lane signals.
These may warn of hazards, speed limits, or alternative routes.
If you’re unsure, take the next exit and check your route safely in a lay-by or service area.
Flashing amber lights warn of hazards such as accidents, fog, or queues ahead. They may also display a temporary speed limit or lane closure.
Do not increase your speed until you see a clear signal confirming it’s safe to do so.
