Everyone is correct, basic two years and then there are opportunities to specialise. Traffic officers are trained to a very high standard of driving of cars and motorcycles, fast roads, escorts & pursuit training, vehicle examination,use of speed & breathalyser equipment and in road death investigation - the more unpleasant yet essential part of being a traffic officer, then there are opportunities to specialise within the dept. Why not see if you could arrange to visit your local traffic dept or have a chat with the traffic officers to see if he's still interested and wish him good luck!
Steve, perhaps you should adhere to speed limits/not use a mobile phone/wear a seatbelt/insure or tax your vehicle/not drink & drive etc can't imagine any other reason why you would want to make such a negative remark.
