How do you become a police driving instructor?

take courses and school

a good school like smart-drivers.co.uk or other good dit trainers.

In Ontario, Canada you have to go to the Ministry of transportation, get a driving instructors package, you have to pay a fee, take the written test and then pass a G2 exit road test. the road test can be done after you complete a driving instructors course. If you fail the road test twice you cannot retest for a year, and make sure you practice the basics before you go test, your bad habits you have will fail you....Also you cannot have any points on your licence and if at any point you have more than 3 points on your licence you lose your driving instructor licence. You will also have to pass a police background check, the ministry does this when you apply.

There are two types of courses: In Car Instructor and In Class Instructor

These courses are offed by Humber College by Canadian prodrivers and by the Ontario safety league
