Why you might see a gritter in summer and how to stay safe on hot roads

We are expecting some hot weather over the coming weeks, with some air temperatures reaching over 30 degrees. With this, our gritters might need to come out – so we’d like to give you a heads-up so you don’t wonder what they’re up to…

What will the hot weather do to our roads?

When the sun is out for a while, it can start to make the tar on the roads much softer than usual, which can alter the way drivers use our roads. It might not always seem too warm at 30 degrees (although it will certainly be ice-lolly weather), the roads absorb the heat, which can make the roads almost 20 degrees hotter than the air. A change in the roads structure can happen, which is similar to melting.

But why the gritters? Aren’t they just for winter?

If the hot weather continues, our grit lorries are on standby to go out and spread crushed rock dust – a common method used to create a non-stick surface and limit damage to the road surface.

Please stay safe while travelling

Drivers can keep themselves, passengers and pedestrians safe by driving a little slower and avoiding heavy braking in affected areas.

  • You have advice on how to drive safe on hot road. But were is the advice on driving safely on your pot hole road?

  • Just to check, this is ‘crushed rock dust’, and NOT rock salt? That makes a big difference to older vehicles made of steel and chrome, their owners don’t like them to rot!

    • Hi Howard, that’s right. The dust would be used to create a non-stick surface and limit damage to the road surface. Thanks ^MY
