Complete a course and get a top 10 time on it. After you get your initials up there, press down until you see the conveyor, then press left. After 30 seconds of holding left, you will see a head go by and it will say ''I love this job''
Now select the Police Car or the School Bus (see the hidden car code on this page) and press BRAKE, BRAKE, GAS while in the race to activate it. The school bus has flashing lights...but the Police Car has cooler flashing lights AND a siren!
