Four components of driving — District of Columbia Permit Test
Four components of driving on the District of Columbia permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The four major components of driving are looking and seeing, thinking and deciding, letting others know what you are going to do, and making a decision.
Most crashes start with one of these steps skipped, like seeing a hazard but never deciding what to do about it.
Four Major Components of Driving
When deciding what to do while driving, choose the action that involves the least risk, because all driving involves some risk.
There is rarely a choice with no danger at all, so the smart move is the one that is least likely to hurt someone.
you will decide what to do on the basis of least risk.
You let other drivers and pedestrians know what you are going to do through hand signals, turn signals, headlights, brake lights, and the position of your vehicle.
Other road users can only stay out of your way if they can tell where you are about to go.
You let them know through hand signals, turn signals, headlights, brake lights, and by the position of your vehicle.

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.
