  • Emergency Refuge Areas (ERAs): Marked with blue signs showing an orange SOS phone symbol. Orange tarmac surface.
  • If you can reach an ERA: Pull in. Hazard lights on. Stay in your vehicle with seatbelt fastened. Use the SOS phone or call 999. Do not attempt to exit the ERA into live traffic.
  • If you cannot reach an ERA: Do NOT stop in a live lane unless absolutely necessary. Hazard lights on immediately. Call 999 immediately – Highways England may need to close a lane.

Breakdown on the M1 – What To Do

Follow these steps if you break down on the M1:

  1. If you are on a smart motorway section (J16-J19): Reach an emergency refuge area (ERA) if possible. If not, hazard lights on, stay in your vehicle, call 999 immediately.
  2. If you are on a traditional hard shoulder (J15-J15a): Pull onto the hard shoulder as far left as possible. Hazard lights on. Exit the vehicle from the passenger side and stand behind the barrier.
  3. If you are in a live lane and cannot move: Hazard lights on immediately. Stay in your vehicle with seatbelt fastened. Call 999 immediately – do not wait.
  4. Do not attempt to cross live lanes to reach an ERA on the opposite side.
  5. Do not attempt to change a tyre or check damage on the motorway – it is too dangerous.

Recovery vehicles cannot close lanes. Highways England must attend first on smart motorway sections or if a lane is blocked.

Emergency Refuge Areas (ERAs) on M1 J16-J19

Emergency Refuge Areas are located approximately every 1.5 miles on the smart motorway section between J16 and J19. Each ERA features:

  • Orange tarmac surface for easy identification
  • Blue sign with orange SOS phone symbol
  • SOS phone connecting directly to Highways England
  • Emergency lighting
  • Safe waiting area behind the barrier

If you break down on a smart motorway section, your goal is to reach the next ERA. If you cannot, call 999 immediately.

Note: Not all ERAs are visible from a distance – look for the blue signs.

Red X Lane Closures – What You MUST Do

If a Red X is displayed above your lane on the smart motorway gantries:

  • You must exit that lane immediately – it is closed for a reason (accident, breakdown, or roadworks ahead).
  • Driving in a Red X lane is illegal and will result in prosecution (cameras enforce this).
  • Move to an open lane only when it is safe to do so.
  • If you cannot move lanes safely, reduce speed and exit at the next junction if possible.

Red X lanes are there for your safety. Someone may be broken down ahead, or emergency services may be attending an incident.
