Road signs and driving rules — with scenario quizzes and reaction-distance calculators.
15 explained questions, each with the answer, a worked explanation, and something interactive to help it stick.
- Which of these causes the most collisions?Distracted driving — driver inattention and human error — causes the most collisions overall; human error is a factor in roughly 94% of crashes. Note the trap: speeding is the leading cause of fatal collisions specifically, but distraction causes the most crashes total.Read the guide
- What is one thing shared lane markings are not used for?Shared lane markings, or "sharrows," are NOT used to decrease the possibility of highway hypnosis. Their real purposes are to position cyclists safely in the lane, mark a lane shared by bikes and cars, and remind drivers to share the road with bicyclists.Read the guide
- Daydreaming while driving is an example of which type of distraction?Cognitive (mental) distraction. Daydreaming takes the driver's mind off the driving task even though the eyes stay on the road and hands stay on the wheel. Because attention — not vision or physical control — is what's diverted, it is classified as a cognitive distraction.Read the guide
- When parallel parking, how close should you leave the curbside wheels?Leave the curbside wheels within about 6 to 18 inches of the curb (most handbooks say no more than 18 inches). On a hill you also turn the front wheels toward or away from the curb so the car cannot roll into traffic.Read the guide
- True or False: The National Safety Council Reports That Distracted Driving Leads to 16 Thousand Crashes Each Year?False. The National Safety Council estimates that distracted driving - especially cell-phone use and texting - causes roughly 1.6 MILLION crashes each year, not 16 thousand. The figure is about a hundred times larger than the statement claims.Read the guide
- Is the Use of Synthetic Marijuana Legal in the State of Georgia?False. Synthetic marijuana is illegal in Georgia. It is classified as a Schedule I controlled substance and was banned under 2012's "Chase's Law," which outlawed the chemicals used to make it, so possessing or using it is a crime even when it is sold in stores.Read the guide
- Why do you need to be prepared for changes in your immediate range?Because at higher speeds your reaction and stopping distance grow sharply and hazards in your immediate range give you very little time to respond. Anticipating changes there lets you brake or steer in time to avoid a collision you could not otherwise stop for.Read the guide
- This is the only BAC level at which safe driving can be guaranteed. What is it?0.00%. Any measurable blood alcohol concentration can impair judgment, reaction time, and coordination, so safe driving can only be guaranteed at a BAC of zero. Even levels well below the legal limit reduce driving ability.Read the guide
- When Parking Parallel, It Is Best to Leave the Curb-Side Wheels How Far From the Curb?When parallel parking, leave the curb-side wheels within about 6 to 18 inches of the curb—most DMV manuals say no more than 12 to 18 inches. This keeps your car close enough to be legal and clear of traffic without scraping or hitting the curb.Read the guide
- Vehicle Skids Are Most Likely to Be Caused By What?Skids are most often caused by the driver: driving too fast for road and weather conditions and then braking, accelerating, or steering too abruptly. These sudden inputs overwhelm the tires' grip, so they lose traction and slide.Read the guide
- What Should You Release to Re-establish Vehicle Control and Tire Traction?Release the accelerator (gas pedal). Easing off the gas reduces the force spinning or sliding the tires, letting them regain grip so you recover steering control. Avoid slamming the brakes, which can worsen the skid.Read the guide
- Why Was Mariah in an Accident and Lost Her Life?Mariah lost her life because she was driving distracted: talking on the phone for directions, she missed her exit and made an unsafe, illegal maneuver (a U-turn) to recover. The phone conversation pulled her attention off the road — a textbook distracted-driving fatality.Read the guide
- What Should You Do When You See a Flashing Yellow Traffic Signal at the Next Intersection?Slow down and proceed with caution. A flashing yellow light means the intersection is not stopped for your direction, so you do not have to stop, but you must reduce speed, stay alert, watch for cross traffic and pedestrians, and yield if necessary.Read the guide
- You Have Allowed the Wheels of Your Vehicle to Run Off the Edge of the Pavement. You Should:Grip the steering wheel firmly, ease your foot off the gas, and brake gently to slow down. Once you have slowed and checked for traffic, steer back onto the pavement smoothly. Do not jerk the wheel or brake hard, which can cause loss of control.Read the guide
- When are lights required to be installed on a trailer?Lights are required whenever a trailer is used on public roads. Every trailer must have tail lights, brake lights, turn signals, a license-plate light, and rear reflectors; larger and wider trailers also need side marker and clearance lights. They are essential from dusk to dawn and in low visibility.Read the guide
