Georgia Pre Trip Test Question Confused

I just got my CDL in Texas. In Texas the pretrip is a WRITTEN test not a hands on practical test.

Hey Hollis are you in a school? Are you working for a company? Just curious because I will be in Dallas Saturday for orientation and a few other students said we have to take more tests when we get there even though we graduated here.

Been watching videos and still don't understand a few things

1.When I start out side i check the lights for damage and proper color ( Are the lights turned on or off for this ?)

2. I says check light on the in cab part ( do i turn on lights and get out and see if they work then get back in to change lights)

3. On the brake check tug test some videos show just the bob tail tractor some show with a trailer hooked . ( does the examiner make you hook to a trailer or un couple if your coupled on pre trip part)

4. Also if your parking brake is on how do you pull on the slack adjuster to show you only have a inch of movement videos ive seen dont show this part

To wrap this up all in one...

1. Lights are off. For each light, I would point to each light calling it out while saying "make sure it's clean, not faded, cracked, broken, or missing. Proper color is...". Example "Headlights - make sure they're clean, not faded, cracked, broken, or missing. Proper color is clear."

2. Checking lights on the in-cab, you're actually looking at the indicators in the dash. As Robert said, the truck will be running at this point. Turn on your headlights and be sure you have dash illumination (might have to fake that a little if it's a sunny day as it might be difficult to see the illumination). Click on the high beams and make sure the high beam indicator light comes on in the dash. Do the same for each turn signal, then the 4-ways.

3. You won't do any coupling/uncoupling while at the DMV. You'll be hooked to a trailer and do the two tug tests (trailer brakes then tractor brakes).

4. As was mentioned previously, you can demonstrate checking the slack adjusters on the steers. On the drive/trailer axles, just describe to the examiner how you would check them (set wheel chocks, release brakes, pull on push-rod/slack-adjuster to be sure it doesn't move more than an inch).

Generally, you'll do the entire external pre-trip (again, engine off, lights off). Then, you'll jump in the truck to do the in-cab inspection including air brake tests. This concludes with the tug tests. In my CDL school's routine, once the tug tests are complete, you then ask the examiner if he/she will help you check your external lights for you. At that point, the examiner will exit the truck and stand in front of it. Then, you'll turn on the headlights, high-beams, each turn signal, then 4-ways. They'll probably give you a thumbs-up after each. Then, they'll go to the rear of the truck, you'll tap the brakes, hit the turn signals, then 4-ways.
