A 30-year-old driver's blood test shows exactly 5.00 nanograms of THC per milliliter within two hours after driving. No cannabis was used after driving. Does this reach Washington's numerical THC threshold?
Correct answer: Yes; the threshold includes exactly 5.00.
The statutory threshold is 5.00 or higher, not strictly greater than 5.00, measured within two hours after driving. The scenario excludes later consumption; impairment can also establish an offense independently of that threshold.

An adult driver is affected by cannabis, but the measured THC concentration is below 5.00 nanograms per milliliter of blood. Does the lower result alone establish that driving was lawful?
Correct answer: No; driving while affected can violate the impairment provisions.
Washington also prohibits driving while under the influence of or affected by cannabis or drugs. The numerical THC provision is not a safe-driving allowance below 5.00.

A 19-year-old has a THC concentration of 1.00 nanogram per milliliter of blood within two hours after driving, with no cannabis used afterward. What does the under-21 rule provide?
Correct answer: A THC result above 0.00 and below 5.00 is covered.
For drivers under 21, this offense includes a THC concentration above 0.00 but below the general DUI threshold. General impaired-driving provisions can also apply; the scenario excludes consumption after driving.

An intoxicated adult remains in actual physical control of a car stopped on the roadway. Does the car's lack of movement alone rule out an offense?
Correct answer: No; actual physical control while impaired can itself be an offense.
RCW 46.61.504 addresses actual physical control, not only driving. Its separate safely-off-road provision has specific conditions; a car stopped on the roadway does not satisfy that description merely by being stationary.

Which circumstance matches the statute's safely-off-road provision for the physical-control offense?
Correct answer: The vehicle was moved safely off the roadway before police pursuit.
The provision requires moving safely off the roadway before being pursued by an officer. It concerns the physical-control section, not permission to drive while impaired or cancellation of an earlier driving offense. Arrange sober transport rather than driving after using impairing substances.

Under Washington's implied-consent statute, when is consent to the described alcohol breath test deemed given?
Correct answer: After driving, if arrested with the specified reasonable grounds.
Operating a vehicle triggers the statutory implied consent, subject to its conditions. The described breath testing follows an arrest where the officer has the specified reasonable grounds; this is not a rule authorizing every test on mere suspicion.

Before the statutory post-arrest breath test, what license consequence must the officer warn can follow refusal?
Correct answer: Revocation or denial of driving privileges for at least one year.
The required refusal warning states revocation or denial for at least one year. Exact consequences and review depend on the applicable process and record; refusal is not a way to avoid license consequences.

Can refusal of the post-arrest breath test be used in a criminal trial under the warning required by Washington law?
Correct answer: Yes; the officer must warn that refusal may be used.
The required warning includes that refusal may be used in a criminal trial. Declining the test does not guarantee that no evidence related to that refusal can be considered.

Besides explaining refusal, which testing right must the officer describe before the statutory breath test?
Correct answer: Additional testing by a qualified person of the driver's choosing.
The statute requires notice of the right to additional tests administered by a qualified person of the driver's choosing, as provided in RCW 46.61.506. Additional testing does not itself erase an official result.

Does refusing the breath test categorically prevent an officer from obtaining a lawful blood test?
Correct answer: No; blood testing may still be authorized by a warrant or other law.
The statute preserves blood testing under a search warrant, a valid warrant exception or other lawful authority. It neither creates a blanket ban after refusal nor authorizes an unlawful blood draw.

A driver receives the statutory notice of a right to a DOL hearing after an implied-consent action. What is the ordinary deadline stated for requesting that hearing?
Correct answer: Within seven days after the notice is given.
The statute specifies a written hearing request within seven days; a mailed request must be postmarked within seven days after receiving the notice. Follow the actual notice for required steps and applicable fees or waiver procedures; do not confuse this deadline with later appeal periods.

A permit holder receives a temporary licensing notice under the implied-consent procedure. Does it grant broader privileges than the permit already allowed?
Correct answer: No; it cannot authorize more than the license or permit it replaces.
The statute says the temporary license is not valid to any greater degree than the license or permit it replaces. Its validity is also subject to the statutory timing and the person's actual licensing status.

An ordinary car has a separate trunk. Where can an opened cannabis package be kept to meet this highway-transport rule?
Correct answer: In the trunk, away from the occupied passenger area.
For an opened package in a vehicle with a trunk, the trunk is the relevant storage exception. The law separately recognizes unopened sealed packages; this answer does not waive other possession or impaired-driving rules.

An adult passenger eats a cannabis edible while the car is on a public highway. Does being a passenger make that consumption permissible?
Correct answer: No; consuming cannabis in the vehicle is prohibited in any manner.
The public-highway rule covers consumption in any manner, including ingesting. Passenger status and a smoke-free method do not create exceptions.

For an adult lawfully possessing cannabis, which package condition is expressly recognized by the vehicle highway-storage rule?
Correct answer: A package never opened, with its seal and contents intact.
The provision recognizes a package that has not been opened, had its seal broken or had contents partly removed. Resealing an opened package is not the same condition. It does not authorize consuming cannabis or driving while impaired.

A vehicle has no trunk. Which location fits the alternative storage rule for an opened cannabis package?
Correct answer: An area not normally occupied or directly accessible to occupants.
For a trunkless vehicle, the alternative must not normally be occupied or directly accessible by the driver or passengers. The statute expressly treats utility and glove compartments as part of the occupied area.
