Jump starting — Louisiana Permit Test
Jump starting on the Louisiana permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When jump-starting, connect the positive post of the dead battery to the positive post of the live battery.
Matching positive to positive keeps current from flowing the wrong way and damaging the batteries.
3. Connect the positive post of the dead battery to the positive post of the live battery.
When jump-starting, connect the negative post of the live battery to the negative post of the dead battery or to the engine block or frame.
Grounding on the block or frame keeps the last spark away from the battery fumes.
4. Then connect the negative post of the live battery to the negative post of the dead battery or to the engine block or frame.
When jump-starting, make sure the two cars are not touching, then start the car giving the jump first.
Cars that touch can let current pass through their bodies and cause sparks.
Make sure the two cars are not touching.
Never light a match or smoke a cigarette near a battery, because battery fumes can cause an explosion.
Batteries give off gas that a spark or flame can set off with great force.
NEVER light a match or smoke a cigarette near a battery.
If you get battery acid on your skin, eyes or car, wash it off immediately with water.
Battery acid burns, and the longer it stays on the worse the damage.
If you get battery acid on your skin, eyes, or car, wash it off immediately with water.
On the test
When jump-starting a car, what do you connect the dead battery's positive post to?
The live battery's positive post. Matching positive to positive keeps current from flowing the wrong way and damaging the batteries. Class D & E Driver's Guide, p.118: “3. Connect the positive post of the dead battery to the positive post of the live battery.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
