A stream of cars is circulating in a roundabout you want to enter. What should you do?
Correct answer: Wait for a safe gap in circulating traffic
Yield to vehicles already circulating. Enter during a safe gap; do not assume circulating drivers must create a space for you.
Source: ADOT, How do I enter a modern roundabout when traffic is congested? — yield at entry. ↗
You reached a roundabout entry before a car reached another entry. Does arriving first give you priority over traffic already circulating?
Correct answer: No; entry depends on a safe gap, not arrival order
A roundabout is not a first-come, first-served four-way stop. Circulating traffic has priority; each entering driver selects a safe gap.

Which way does normal traffic circulate around the central island of an Arizona modern roundabout?
Correct answer: Counterclockwise
Traffic circulates counterclockwise around the center island. Follow the entry and one-way controls rather than turning against circulation for a shorter route.
Source: ADOT, Is a modern roundabout like a four-way stop? — direction of circulation. ↗
A roundabout approach has a posted 15 mph limit. You remember general roundabout advice mentioning 25 mph. Which should guide this approach?
Correct answer: Slow to the posted limit, or less if needed
Follow the posted speed limit and drive with care. A general range used to describe roundabouts does not override a lower posted limit or unsafe conditions.

A 45-foot vehicle combination needs extra lane space to negotiate a roundabout. Must it remain entirely in one lane regardless of its turning path?
Correct answer: No; necessary lane deviation is permitted with due care
A vehicle or combination at least 40 feet long or at least 10 feet wide may deviate from its lane as necessary to approach and drive through a roundabout, with due regard for other traffic.
Source: Arizona Revised Statutes 28-778, subsection A. ↗
You and a 45-foot truck are about to travel through a roundabout so closely that your paths would create an immediate hazard. What must you do?
Correct answer: Yield to the truck, slowing or stopping if necessary
When approaching or driving through a roundabout, yield to a qualifying large vehicle going through at the same time or close enough to create an immediate hazard. Slow or stop if necessary.
Source: Arizona Revised Statutes 28-778, subsection B. ↗
You are already driving through a roundabout. A large truck is still approaching its entry. Does the large-vehicle rule itself require you to stop in the circle to let that approaching truck enter?
Correct answer: No; the rule preserves this circulating-vehicle distinction
The statute expressly does not require a driver already traveling through the roundabout to yield to a qualifying large vehicle that is merely approaching it. Continue cautiously and do not create a collision; this is not permission to ignore an actual hazard.
Source: Arizona Revised Statutes 28-778, subsection B. ↗
Your car-and-trailer combination is 42 feet long. A 45-foot truck is on your left as both approach a roundabout closely enough to conflict. Who yields under the large-vehicle rule?
Correct answer: You yield, because your qualifying combination is on the right
When two qualifying vehicles or combinations approach or travel through a roundabout at the same time or so closely as to create an immediate hazard, the driver on the right yields to the driver on the left.

Your active freeway ramp meter is red, but the freeway looks clear. What should you do?
Correct answer: Stop for the red signal
A ramp-meter red signal must be obeyed like another red traffic signal. Light traffic does not authorize running it.
Source: ADOT, Ramp Meters: Unappreciated or just misunderstood? — obeying the red light. ↗
A ramp meter is signed ONE CAR PER GREEN. The car ahead enters on green and you are close behind. What is required?
Correct answer: Wait for your own green indication
The green release is for one car under this control. Do not follow another vehicle through on its release.
Source: ADOT, Ramp Meters: Unappreciated or just misunderstood? — one car per green. ↗
You reach an active ramp meter as your green appears, without having stopped and with no vehicle ahead using that release. Must you still stop at the meter before proceeding?
Correct answer: No; proceed if it is safe to do so
ADOT allows proceeding without first stopping when the driver reaches green and it is safe. Approach prepared to stop; red and one-car-per-green controls still apply.
Source: ADOT, Ramp Meters: Unappreciated or just misunderstood? — green before stopping. ↗
Signs direct queued traffic to use both open lanes until a zipper-merge point. Where should you normally merge?
Correct answer: At the designated merge point
Where a zipper merge is in place, follow its signs and use the available lanes to the merge point. This guidance does not permit using a closed lane or the shoulder.
Source: ADOT, Let’s talk zipper merge — using lanes until the final merge point. ↗
You reach the signed zipper-merge point beside another queue of traffic. How should the two queues combine?
Correct answer: Take turns, one vehicle from each lane
Alternate vehicles at the merge point. Leave room for the next vehicle rather than blocking drivers who used the other open lane as directed.

On a divided highway, a vehicle is coming toward you against traffic. What response does ADOT recommend?
Correct answer: Ease off the accelerator, check adjacent space and steer away
Reduce speed, confirm the space beside you is clear, and steer away from the threat. Once in a safe place, call 911 to report the wrong-way driver.
Source: ADOT, Wrong-Way Drivers — What should I do if I encounter a wrong-way driver? ↗
An overhead freeway sign warns of a wrong-way driver ahead. You have not yet seen that vehicle. What should you do?
Correct answer: Safely head toward the nearest highway exit
ADOT advises safely moving toward the nearest highway exit as soon as possible after this warning. Do not make an abrupt unsafe maneuver or cross a prohibited divider.
Source: ADOT, Wrong-Way Drivers — What should I do if I see an overhead sign warning of a wrong-way driver ahead? ↗
You miss a freeway exit and see a low grassy divider between the two roadways. There is no authorized crossover or opening. May you drive across it to turn back?
Correct answer: No; do not cross the dividing space
A divided highway's intervening space or barrier is not a shortcut. Crossing must use an opening or a crossover or intersection established by public authority, with applicable traffic controls obeyed.

During a posted two-person HOV restriction, an ordinary car carries its driver and one passenger. Does that meet the occupancy count?
Correct answer: Yes; the driver counts as one of the two people
The two-person requirement includes the driver. A driver plus one passenger meets that count; continue to follow lane and traffic controls.
Source: Arizona Revised Statutes 28-737, subsection A. ↗
ADOT's standard Phoenix-area HOV weekday schedule is posted. Which periods have occupancy restrictions Monday through Friday?
Correct answer: 6–9 a.m. and 3–7 p.m.
ADOT lists 6–9 a.m. and 3–7 p.m. on weekdays as the restricted periods. Read the signs governing the lane you are using.
Source: ADOT, High Occupancy Vehicle (HOV): HOV Lane Rule Changed — When are HOV lanes restricted to specific vehicles? ↗
In September 2026, a solo driver has an ordinary alternative-fuel car with Energy Efficient plates and no other exemption. Do those plates alone allow HOV use during two-person restricted hours?
Correct answer: No; that single-occupant exemption ended in 2025
The federal exemption ended September 30, 2025. Alternative-fuel status or Energy Efficient plates alone no longer excuse having fewer than two occupants during restricted times.
Source: ADOT, High Occupancy Vehicle (HOV): HOV Lane Rule Changed — What Changed on Sept. 30, 2025? ↗
You see a motorcycle with one rider in an HOV lane during restricted hours. Does Arizona require that motorcycle to carry a passenger to qualify?
Correct answer: No; motorcycles have an occupancy exception
Arizona's HOV occupancy restriction expressly excludes a person driving a motorcycle. Do not assume a solo rider is violating the carpool rule.

You borrow a relative's car displaying valid disability plates, but you are not transporting the person entitled to them. May you use a marked accessible space for your own shopping?
Correct answer: No; the valid plates alone do not authorize that use
The marked space is for a vehicle transporting the person issued the valid placard or access plates, with the required display. Borrowing the vehicle does not transfer that eligibility to an unrelated trip.
Source: Arizona Revised Statutes 28-884, subsection A. ↗
Your car displays a valid disability placard. May you stop in the striped access aisle beside an accessible parking space?
Correct answer: No; the access aisle must remain clear
The prohibition on stopping, standing or parking in an access aisle includes vehicles displaying access plates or placards. The aisle provides access to an accessible route of travel.
Source: Arizona Revised Statutes 28-884, subsection C. ↗
You are chauffeuring a person with a physical disability in a car without a placard. May you momentarily use the marked accessible space solely to load or unload that person?
Correct answer: Yes; this momentary loading or unloading exception applies
Arizona provides this limited exception for momentarily loading or unloading a person with a physical disability. It does not authorize ordinary extended parking or use of the access aisle.

A legally blind pedestrian with a predominantly white cane is crossing your path. What does Arizona require?
Correct answer: Yield and take reasonable precautions to avoid injury
Yield the right-of-way and take reasonable precautions to protect the pedestrian. The rule also covers specified service-animal or sighted-person assistance.
Source: Arizona Revised Statutes 11-1024, subsection I. ↗
A pedestrian who is blind is not carrying a cane or accompanied by a service animal. Does the absence of those aids remove the person's ordinary pedestrian rights?
Correct answer: No; the person retains the same pedestrian rights
The statute preserves the pedestrian's rights whether or not a cane, service animal or sighted helper is present. Do not assume that every disability is visible or that an aid is required for ordinary pedestrian rights.
Source: Arizona Revised Statutes 11-1024, subsection I. ↗
A motorcycle occupies part of a traffic lane. May you squeeze your car alongside it in that lane to pass?
Correct answer: No; the motorcycle is entitled to the full lane
Motorcycles are entitled to full use of a lane. Do not drive a car in a way that deprives a rider of that space; plan any pass using a lawful, safe lane change.
Source: Arizona Revised Statutes 28-903, subsection A. ↗
Traffic is stopped on a street with two lanes in the same direction and a 45 mph limit. A two-wheeled motorcycle safely filters between stopped vehicles at 15 mph. Is that necessarily unlawful?
Correct answer: No; those conditions fit Arizona's filtering exception
The exception permits safe filtering past stopped same-direction vehicles on a street with at least two adjacent same-direction lanes, a limit no higher than 45 mph, and motorcycle speed no higher than 15 mph. It is not general permission to split moving freeway traffic.

Parked facing uphill at a substantial right-hand curb, which front-wheel position helps the curb check a backward roll?
Correct answer: Away from the curb
Angle uphill wheels away; let the tire rest gently against the curb.
Source: California DMV, Driver’s Handbook — Parking on a Hill; headed uphill. ↗
You park on the right side of a hill with no curb. Where should you point the front wheels?
Correct answer: Toward the right-hand road edge
Without a curb, aim toward the road edge to direct a possible roll away from traffic.

On a two-way road, you are 80 feet before a railroad grade crossing and want to move left of center to pass a car. Is that permitted?
Correct answer: No; do not pass left of center there
Arizona prohibits driving left of center when approaching within 100 feet of a railroad grade crossing or traversing it. The section has a one-way-roadway exception; this scenario specifies a two-way road.
