Road test

I took my road test for my driver's license at the Melrose armory.

The guy had me turn on the car and operate my turn signals and brakes while he checked the front and back blinkers and brake light. Didn't have me demonstrate the headlights or hazards or anything else.

The test was mostly conducted on quiet but narrow, unmarked, and poorly maintained roads. He had me do a three-point turn on a narrow road; the Mazda 5 has an excellent turning radius so it was pretty easy, though I hit the curb with my undercarriage. At the intersection after that I asked which way I should turn, and he said "you decide." I arbitrarily chose right; apparently I missed a "do not enter" sign to the left and I would probably have autofailed if I had gone left. Yay winning the coin toss. He had me pull over up to the curb and then back up along the curb for a while. He had me pull over and park on a hill (so, know which way you're supposed to turn the wheels when parking on a hill from the driver's manual; I guessed and I think happened to be correct). He had me parallel park behind a car; I did a somewhat lousy but workable job on the initial approach, and he didn't wait for me to adjust before having me pull out again.

That was about it. He didn't tell me if I lost points for anything, just filled out the "you passed" paperwork. The whole process was pretty fast; I showed up half an hour early and was done before my scheduled time.


Re-learning how to drive was pretty easy. Learning how to parallel park was not. My advice based on my experience:

1. The driver's manual contains a precise, rigid formula for parallel parking which makes it sound easy. Ignore this; it won't work.

2. If you're having any issue clearing the rear left corner of the car you're parking behind, start further back, or don't turn the wheel all the way to the right until after you've started backing up. Your primary concern should be your distance to the curb when you unturn, and you don't want the additional constraint of not hitting the car in front of you. (In real life, if you're parking between two cars with a tight space between them, starting too far back will cause you to fail, but when you're first learning you just want to be parking behind a car with lots of space behind it.)

3. Don't try to get your parking perfect on the initial approach; instead, try to be about 18" away from the curb, and get good at adjusting. If you aim for 6" from the curb and wind up hitting the curb before you're almost done unturning, you've lost; but even if you wind up three feet from the curb you can laboriously adjust your way to parked.

4. A large part of the learning process is getting a good feel for navigating a car backwards. It might be helpful to practice doing that in an empty lot. I didn't wind up doing that personally.

Congratulations!

To parallel park, I ended up memorizing a rigid formula that worked *for the car I was driving*. Luckily it mostly works for the new car too. Also, it's easier on ice.

Yay for passing. Once you have your license you can practice the hard stuff more.

Don't try to get your parking perfect on the initial approach

Oooh. Hmm. Nowadays, if I don't nail it on the first time, I don't try to back-and-forth make it better: it's much much easier for me to start completely over.

For me: front wheels turn as soon as rear wheels clear the front car. How much they turn, nrrr, that I can't say, but basically you want to decisively move from going straight backward to your picked angle. Once your left rear wheel clears the left side of the park cars, immediately start unwinding your front wheels.

Oddly enough, going faster makes it easier: you have so little time to wind up / unwind your front wheels that you slam the wheels over and bang, you're in. :) Okay, perhaps "bang" is a, ah, poor choice of wording. :)

Most people, I find, don't know when to start unwinding the wheel, and the key is the left rear wheel breaking the plane of the left side of the parked cars.




Best way to practice driving backwards: find an empty parking lot. Drive backwards straight as if you're looking for a parking spot. Overcorrection is what kills people: we do it naturally going forward without thinking.




Now you just need to learn how to backup into a parking spot. I still think the graduating test for that is backing up an ambulance into the Brigham & Women's ER bay, although I was a wuss and only did it in a van-style ambulance, not a box-style (boxes are wider. Much wider). ;)

congrats!
I still don't know why they care about backing up along the curb so much. maybe it's just to make sure you can in narrow city streets?... :::shrug:::

Parking on a slope

When parking on a slope, turning the wheels is all about "if the car rolls." If there is a curb you turn the wheels so that should the car roll, it immediately bumps the curb. This stops the car. If there is no curb, you turn the wheel so the car doesn't go into the street. This minimizes velocity before your car bumps into something and keeps you from blocking the street.

For me, it's a lot easier to rederive which way to turn the wheels from "what if it rolls" than it is to have a set of rules based on uphill, downhill, curb, no curb, left side, and right side of the street.

OTOH, I could never figure out which way was which was until someone told me that for uphill, you turn the wheels out *and jam them up against the curb*. Otherwise, it seemed like I'd always want the wheels the same direction (toward the curb), so that the arc of the turn is toward the curb.

I am going to take my test this week in melrose armory, Do you know where did they take you? So I can tour the area before I take the test. Thanks!

Based on vague memories and Google Maps, it looks like Derby Rd. and Mt. Vernon Ave, just north of the armory, would be the places to look at.

Good luck!

Thanks! I went there today, a lot of hills, I guess they will ask me about parking on a hill. I have a question, if they ask you to park on a hill, do you actually turn your wheel and TOUCH the curb, or just turn your wheel but keep the wheel in a safe distance from the curb? I know it an automatic fail to hit the curb! The driver manual do not say anything about this. Thanks again.

He did ask me to park on a hill, yes. I'm pretty sure you can just turn the wheels, and not actually touch the curb. The idea is that if the car starts rolling downhill, the front wheels will hit the curb after just a few inches and stop the car.
