The correct order to park a car is to apply the parking brake first, then shift into Park, and finally turn off the ignition. This sequence protects your transmission and is the standard safety procedure mandated by professional driving programs. The primary mechanical reason is to prevent the vehicle's weight from resting on the transmission's parking pawl, a small component not designed to hold the full load, especially on slopes.
Reliable industry training, such as the Amazon Delivery Service Partner (DSP) driver certification, strictly enforces this "Parking Brake to Park" order to eliminate rollaway risks. Data from transmission repair specialists indicates that repeated stress on the parking pawl can lead to premature wear and costly repairs. The distinct "clunk" heard when shifting out of Park on an incline is a direct symptom of this stress.
For optimal mechanical care, particularly on steep hills, a refined procedure is recommended by automotive engineers. This involves stopping with your foot on the main brake, shifting to Neutral, applying the parking brake firmly, and then gently releasing the foot brake. This allows the vehicle's weight to fully transfer to the parking brake system. Once settled, re-apply the foot brake, shift to Park, and then shut off the engine.
Adhering to this method ensures long-term transmission health and aligns with global best practices for vehicle safety and longevity. It is a simple habit that significantly reduces wear on critical components.

















As a driving instructor for over a decade, I drill this sequence into every student: "Brake, Handbrake, Park, Off." It's non-negotiable. I've seen the aftermath of cars rolling away because someone skipped the parking brake. In our tests, we actually demonstrate the "clunk" from the transmission when you do it wrong. That sound is a teaching moment—it’s the sound of unnecessary strain. So think of the parking brake as your primary holding device; Park is just the backup. Make it a muscle memory habit every single time.

Look, I’m a mechanic, and I see the insides of transmissions. That little parking pawl? It’s not a tow hook. When you park on a hill and just slam the shifter into ‘P’, all that car weight is hanging on this tiny piece of metal. Do that daily, and you’re asking for trouble—a worn pawl that might not engage properly, or worse. The proper sequence lets the actual brakes do the heavy lifting. It takes two extra seconds. My advice is simple: stop, put it in neutral, pull the handbrake up until it’s firm, let the car settle, foot back on the brake, then into Park. Your transmission will thank you in 100,000 miles.

Honestly, I used to just throw it in Park and get out. Then I read my car's owner’s manual. It explicitly says to apply the parking brake first to reduce load on the transmission. That was a lightbulb moment. Now I do it every time, whether I’m on a slope or not. It’s just part of the routine. It feels more secure, and I don’t get that jarring lurch when I shift out of Park anymore. It’s a small step for better car care that anyone can adopt just by reading the instructions they already have.

Managing a fleet, our top priority is safety and minimizing costs. We enforce a strict parking protocol: parking brake fully engaged before selecting Park. This isn’t a suggestion; it’s a policy logged in our driver training modules. The rationale is twofold. First, it’s a critical safety redundancy to prevent vehicle movement. Second, from a pure cost-of-ownership perspective, transmission repairs are a major expense. By standardizing this practice, we’ve observed a measurable reduction in transmission-related complaints. For commercial operators, it transforms from a "good practice" into a clear operational and financial imperative. Consistency across all drivers is key.
