Traffic Stop 15G
Disable a suspect vehicle with help from your partner.

---

Cases: A Marriage Made in Heaven [Traffic], The Fallen Idol [Traffic], The Red Lipstick Murder [Homicide], The Silk Stocking Murder [Homicide], The White Shoe Slaying [Homicide], The Studio Secretary Murder [Homicide], The Black Caesar [AD Vice] & The Gas Man [Arson].
Street Crimes: Thicker Than Water [Homicide], Fatal Plunge [AD Vice], Paper Sack Hold-up [Arson] & Hot Property [Arson].

Again, you'll have ample opportunities to gain this. In many cases and street crimes a suspect will get in their car and try to drive away from you, so take flight and drive after them.

To get your partner to fire shots at the fleeing suspect, you need to get up and close to them and make sure you're on the left side of their car. This is so he can hang out of the window and fire his weapon. Simply get in close and as your partner fires off the odd shot, one or two will hit the wheels of the car. Once that's happened, drive up to the side of them and ram them off the road. The suspects car will then come to a halt, so jump out your car and apprehended them for the achievement to unlock.
