Summit Garage Expert Advice

Driving on the motorway is very different from regular roads. Higher speeds, faster traffic flow, and longer journeys all require extra awareness and good vehicle preparation. At Summit Garage, we often see breakdowns that could have been avoided with a few simple checks before joining the motorway.

This guide covers everything you need to know to stay safe, confident, and prepared.

Before You Join the Motorway

A few quick checks can make a big difference:

  • Tyres: Ensure correct pressure and adequate tread depth
  • Oil & fluids: Check engine oil, coolant, and screen wash
  • Fuel: Make sure you have enough fuel for your journey
  • Lights: Check indicators, brake lights, and headlights
  • Windscreen: Clear any cracks and ensure good visibility

A well-maintained vehicle reduces the risk of breakdowns at high speed.

Joining the Motorway Safely

The slip road is designed for safe entry:

  • Build up speed to match motorway traffic
  • Use your mirrors and blind spot checks
  • Signal clearly before merging
  • Join smoothly without forcing other drivers to brake

Remember: traffic on the motorway has priority.

Driving on the Motorway

Once you’re on the motorway, keep these key rules in mind:

Stay in the left lane

Unless overtaking, you should remain in the left-hand lane.

Overtaking safely

  • Use the middle or right lane only to overtake
  • Check mirrors and blind spots carefully
  • Return to the left lane once clear

Maintain safe distance

Use the “two-second rule” as a minimum gap, increasing it in poor weather.

Keep a steady speed

Avoid unnecessary acceleration and braking to improve safety and fuel efficiency.

Common Motorway Mistakes to Avoid

  • Sitting in the middle or right lane unnecessarily
  • Tailgating other vehicles
  • Sudden lane changes without checking blind spots
  • Driving too slowly for conditions
  • Ignoring warning signs or variable speed limits

These habits increase accident risk and traffic congestion.

What to Do in a Breakdown

If your vehicle develops a problem:

  1. Move to the hard shoulder or emergency refuge area if possible
  2. Turn on hazard lights immediately
  3. Exit the vehicle from the left side if safe to do so
  4. Stand behind the safety barrier
  5. Call breakdown assistance or emergency services

Never attempt repairs in an unsafe location.

Motorway Driving in Bad Weather

Conditions can change quickly at higher speeds:

  • Increase following distance in rain, fog, or snow
  • Use dipped headlights in poor visibility
  • Avoid sudden braking or steering movements
  • Reduce speed when necessary

Smooth, controlled driving is essential in poor conditions.

Fuel, Rest & Long Journeys

On longer motorway trips:

  • Plan fuel stops in advance
  • Take regular breaks (every 2 hours is recommended)
  • Stay hydrated and avoid fatigue
  • Share driving where possible

Tired driving is one of the biggest motorway risks.

Key Takeaways from Summit Garage

Motorways are among the safest roads in the UK when used correctly, but high speeds mean small mistakes can have bigger consequences. A well-maintained vehicle and attentive driving make all the difference.

If you’re unsure about your car’s condition before a long journey, Summit Garage can carry out a full safety check to give you peace of mind.

How does a motorway work?

Motorways are high-speed roads designed for long-distance travel, using slip roads, multiple lanes, and strict rules to maintain safe traffic flow.

When would you use the right-hand lane on a three-lane motorway?

You should only use the right-hand lane to overtake slower traffic, returning to the left when safe.

When should you use the left-hand lane of a motorway?

The left-hand lane should be used for normal driving at all times, unless overtaking or avoiding hazards.

How should you use the lanes on a motorway?

– Left lane: normal driving
– Middle lane: overtaking
– Right lane: overtaking faster vehicles
Always return left when it is safe to do so.

What is the hard shoulder on a motorway?

A hard shoulder is an emergency stopping lane used only for breakdowns or emergencies (unless used as a running lane on some smart motorways).

When are you allowed to stop on a motorway?

Only in emergencies, breakdowns, or when directed by authorities or road signs.

What to do if you break down on the motorway?

– Pull onto the hard shoulder or emergency area
– Turn on hazard lights
– Exit safely if possible
– Stand behind the barrier
– Call breakdown assistance

How should you rejoin the motorway after a breakdown?

– Build up speed safely
– Check mirrors and blind spots
– Signal clearly
– Merge when it is safe

Can you undertake on a motorway?

Undertaking is generally not allowed, except in slow-moving congestion where lanes are moving at different speeds or you are directed otherwise.

What is bunching on a motorway?

Bunching happens when vehicles travel too closely together, often due to inconsistent speeds, which increases congestion and accident risk.

What helps to reduce traffic bunching on a motorway?

Several factors help reduce bunching and improve traffic flow:
– Maintaining a steady, consistent speed
– Keeping a safe following distance (at least 2 seconds)
– Avoiding unnecessary braking and acceleration
– Using cruise control where appropriate
– Staying in lane instead of frequent lane switching
– Following variable speed limits on smart motorways
Smooth driving behaviour is key to preventing “stop-start” traffic waves.

What is the speed limit on a motorway?

The national speed limit is 70 mph for cars and motorcycles, unless otherwise signposted.

What is the minimum speed on a motorway?

There is no set minimum speed, but you must not drive so slowly that you cause danger or obstruction.

What is a smart motorway?

A smart motorway uses variable speed limits, CCTV, and lane control systems to manage traffic flow and reduce congestion.

Do motorway speed cameras flash in front or behind?

Most use rear-facing or infrared technology, so flashes are often not visible.

Can learner drivers go on the motorway?

Yes, but only when:
– Accompanied by an approved driving instructor
– Driving a dual-control vehicle

Can I drive on the motorway with a provisional licence?

Only if you are with an approved instructor in a dual-control car.

Which vehicles are prohibited from using the motorway?

Not allowed:
– Pedestrians
– Cyclists
– Horse riders
– Certain slow or unsuitable vehicles like tractors

Are tractors allowed on the motorway?

No, tractors are not permitted due to their low speed and safety risks.

Can you tow a car on the motorway?

Yes, but only in emergencies and you should leave the motorway at the earliest opportunity.

What is a contraflow system on a motorway?

A contraflow system involves:
– Temporary lane shifts
– Reduced speed limits
– Narrow lanes
– Barriers separating traffic directions

What colour are the reflective studs between a motorway and a slip road?

The reflective studs between a motorway and a slip road are typically green, marking slip road entry and exit points.

Where are amber reflective studs found on a motorway?

Amber studs are found on the right-hand edge of the motorway, marking the boundary with the central reservation.

Where would you find green reflective studs on a motorway?

Green studs indicate slip roads and junctions, helping drivers identify entry and exit points.
