Testing in domestic grasstrack

[Sings4Speedway 3,246]

As the title states does anyone know if drink/drug testing takes place in domestic grasstrack meetings? Obviously it takes place in Speedway & Continental Longtrack meetings as there have been recently publicised failures but not sure if i have ever heard of anything other than fuel testing at UK grasstracks?

Yes it does. They were testing at the last meeting at Frittenden.
