Don't Worry, It's Not That "Parallel Parking" from Back Home Honestly, many people get scared by the term "parallel parking," thinking it's the tight spot between cars. In reality, the California DMV test focuses on Curb Parking. The examiner will have you pull over on a wide street, then back up in a straight line. Although there's plenty of space, the requirements for distance and observation are extremely strict. ### 1. The 18 Inches: California's Make-or-Break Rule The law requires your right tires to be 12 to 18 inches (30-45 cm) from the curb.

  • Too far: Over 18 inches, you lose points. If you stop in the middle of the road, it's an automatic fail.
  • Too close/hitting: Scraping the curb usually costs points; a hard hit or riding up on it is a critical error and an instant fail. ### 2. The Three-Step Curb Parking Routine 1. Signal and Look: When instructed, turn on your right signal, check your mirrors, and must turn your head to check the right blind spot (Blind Spot Check Guide).
  1. Find a Reference Point: When you see the curb cut into the area of your door handle in the right side mirror (varies by car), slowly straighten the wheel.
  2. Straighten the Car: Use your mirrors to confirm the car is parallel to the curb. ### 3. Straight-Line Backing: Don't Just Stare at the Screen After you stop, the examiner will say: 'Back up in a straight line.' Here's what to do:
  • Position: Place your right hand on the passenger seat back, turn your body to the right rear, and look directly backward.
  • Observation: You cannot rely solely on the backup camera! Only glance at it occasionally.
  • Distance: Back up about three car lengths, keeping the car straight and maintaining the same distance from the curb. > Instructor's Tip: If you notice you're crooked, you can make small adjustments while backing. But don't overdo it. The California parking-rules test your control over the vehicle's position. ### Frequently Asked Questions (FAQ) Q: Can I just use the side mirrors when backing up?

A: No. The examiner requires you to turn your head and look backward—this is a strict safety requirement. Q: Can I keep both hands on the wheel while backing?

A: It's recommended to steer with your left hand (at the 12 o'clock position) and place your right hand on the passenger seat back. This gives you the most stable posture and the best field of view. Q: What if the curb is full of parked cars and there's no space?

A: The examiner will choose a spot with enough room. If they give the instruction, there must be a space ahead—slow down and look for it early.
