A Lanarkshire woman allegedly tailgated her partner’s car before confronting him with threats.
Carole Martin, 46, is accused of driving dangerously on Kingsway, East Kilbride, on July 21.
She allegedly broke the speed limit, drove alongside the car in which the victim was travelling and swerved in front of it.
The charge also states Martin drove too close behind the vehicle, slapped on her brakes for no good reason and caused other road users to take evasive action.
A second charge alleges she acted in a threatening or abusive manner towards the victim.
Martin, of Fergusson Place, East Kilbride, pleaded not guilty to the charges at Hamilton Sheriff Court.
She faces trial next month.
