Basically i was a police officer the other day, and i wanted to catch speeders, however how would i know if anyone is speeding, i mean i want to catch what speed they are actually going at
Upon joining the job of Traffic Officer, you will receive a 'Speed Camera' which will be in your 5th inventory slot.
To use it, left click on a vehicle with it, you will be locked onto the vehicle and the speed will be tracked while you are locked on.
Compare the speed to the speed limit, good luck!
So, you when you join the traffic officer job, take your car and go make a checkpoint. I would make it at the highway before the bazaar where the double line ends. Once you are finished with that get out of your vehicle, put some barricades behind your car and go to a safe spot to not get ran over. Equip your camera and left click at all the cars coming by. You will see their exact speed. Hope this proved helpful.
