I split a heavy forelock and put it over the top of the blinkers, If the forelock blows between the eye and the blinker the horses cannot see forwards. If anything happens the horses cannot see and my Driving instructor will not have M&M competing at her events without forelocks secured in some way. She had someone's team gallop into the side of her car once when the splinter bar broke and the team ran off without the cart. The horses had a lot of forelock in their blinkers and they galloped straight into the side of her car.
