Should You Use the Handbrake When in Park? Here's What Every Driver Should Know

If I’ve already shifted into Park, do I still need to pull the handbrake?

It’s a common question among drivers, especially for those driving automatic transmission cars. Since gear P (Park) already locks the wheels, using the handbrake may seem unnecessary. But in reality, applying the handbrake is still highly recommended, and here’s why!

Why You Should Use the Handbrake Even When in Park

Even if your car is already in gear P, using the handbrake provides an extra layer of safety and protection for your vehicle. Here are the key reasons:

• Reduces stress on the transmission: When parked without the handbrake, the full weight of the vehicle rests on the transmission lock (a component inside the gearbox). Over time, this can lead to unnecessary wear and potential damage.
• Prevents damage from sudden impacts: If your car is hit from behind—especially in a tight parking space—the transmission can get damaged if the handbrake isn’t engaged.
• Enhances overall safety: On slopes or inclines, the handbrake ensures the car stays securely in place, even if the transmission fails.
• Smoother gear shifts later: Releasing the car from Park becomes easier, with less gear grinding, since the vehicle’s weight isn’t locked into the transmission alone.

Which Comes First: Park or Handbrake?

The best practice is to apply the handbrake first, then shift into Park. Doing so ensures that the handbrake—not the transmission—takes the car’s weight. This reduces long-term stress on the transmission locking pin and keeps your car in better condition.

What About Traffic Lights? Park or Neutral?

When stopped at a red light:

• Use Neutral (N) and apply the handbrake

• Avoid using Park (P), especially in traffic, because:

  • You could accidentally shift into Reverse (R) when moving off again
  • If you're rear-ended while in P, the transmission may suffer serious damage

Final Thoughts: Always Use the Handbrake! It’s a Small Habit with Big Benefits

Even if your car doesn’t move when in Park, using the handbrake every time you stop can prolong the life of your transmission, improve safety, and prevent avoidable repairs. It's a simple habit that can make a big difference in the long run!
