Vehicle Safety Report

A total of twelve students and one instructor from Physics: Heat, Electricity, and Magnetism performed standard safety checks on a total of forty-eight student vehicles Tuesday, April 28th.

Thanks to students Andrew, Thomas, Clark, Sierra, Steven, Arthur, Carolyn, Matthew, Stephenie, Jacob, Wesley, Sylvester, and Andrew for all their hard work, their superior appreciation for the finer points of vehicle safety, and their high regard for their classmates' lives and property.

There was high demand for our services, the most ever, and we were short staffed at times, so I couldn't get photos of each student worker, as I have done in the past. Apologies for that.

Most vehicles passed inspection. Vehicles were, on the average, noticeably safer than in the past.* Several more egregious safety concerns were noted that would have almost certainly related in a holiday travel "fail" and possibly a stranding, or worse, an accident:
  • Several vehicles were significantly low on oil, up to three quarts down. When you only have one or two quarts of oil remaining in your engine, the engine will begin to overheat because that little oil can't do such a great job of cooling and lubricating. You also might want to know why your oil is so low. Most likely you are leaking it or burning it. Either way, you must now monitor your oil level more carefully or you will cause a catastrophic engine failure, called a seizure. Essentially, your pistons will stick to your cylinder walls and/or your main bearings will stick to your crankshaft. Check the oil level every time you get gas. Write down how much you add, when you added it, and the odometer reading each time you check. Check the ground under where you park for signs of a leak. Monitor your oil pressure light or pressure gauge, check engine light, and temperature gauge. Hopefully, you'll figure out how much oil you're using and find the leak if there is one, then get it fixed.
  • Many vehicles had tires that had only a millimeter or two of tread remaining. The Maine regulations require at least a millimeter all round, but this isn't enough for Maine summer driving conditions if there is heavy rain or mud on the roads, especially in a rear-wheel drive vehicle. These students were advised to get new tires, preferably before taking any long trip.
  • Although a few were five or slightly more PSI down, no tires had dangerously low tire pressure. This is a first. Maybe our efforts to educate about such things are paying off!
  • Two vehicles had scored and rusty disc rotors visible through aluminum wheels. If disc rotors are scored, they need to be replaced or turned down on a lathe. Replace pads at the same time, and do at least the rear or front brake sets together, if not all four sets. If they are rusty, your brake caliper is not working and needs to be repaired. This is a very dangerous condition on any vehicle.
  • For the second time in a row, several students did not know how to turn on their headlights manually. Automatic headlights are fine, but Maine law requires you to have the headlights on whenever the wipers are turning, so you need to know where this switch is! Consult your owner's manual. You can get copies of your manual online if you have lost or never had yours.
That concludes our biannual community vehicle safety report. If you didn't get chance to get your vehicle checked out yesterday and are worried about the drive home, stop me or one of our student volunteers and ask us about it, or take it to a shop for a check up before your drive home.
