Use your turn signal to avoid getting knocked

I just want to advise the company Lombard tyres to tell their driver of a Toyota Hilux white bakkie who drove on the M5 today (HG 36NJ GP) registration to please his indicator, the colored guy I almost knocked, had an incident where another young guy thought he can do as he pleases, i am fighting with the persons insurance outsurrance for the last few months, I have been knocked, this fool think I can brake in time,he needs to learn to use an indicator cause if it was a cop driving at the back, his brain will have kicked in to avoid trouble, the guy was around 14:30 pm on the M5. Stay safe
