  1. ARefusing one test but agreeing to another will avoid license suspension.
  2. BThe choice is only offered if a breathalyzer is unavailable.
  3. CThe officer can legally insist on a blood test if they suspect drug impairment.
  4. DThe driver has an absolute right to choose which test to take.
Show answer & explanation

Correct answer: C. The officer can legally insist on a blood test if they suspect drug impairment.

While drivers generally have a choice between a breath or blood test, California law allows an officer to legally insist on a blood test if they reasonably suspect drug impairment, as breath tests primarily detect alcohol. If a driver refuses the blood test in this scenario, it constitutes a refusal under implied consent.

Why the other options are wrong

  • A. Refusing any validly requested chemical test constitutes a refusal under implied consent and will lead to license suspension.
  • B. The choice is usually offered, but the officer's discretion regarding suspected drug impairment is a key exception.
  • D. This is generally true for alcohol-only suspicion, but there are exceptions, particularly for suspected drug impairment.

Chemical Test Choice (CA DUI)

Drivers lawfully arrested for DUI typically have a choice between a breath or blood test, but officers can require a blood test if drug impairment is suspected.

  • Choice between breath or blood for alcohol.
  • Officer can insist on blood test for suspected drug impairment.
  • Urine test may be offered if breath/blood unavailable or for specific drug types.
  • Refusal of any validly requested test leads to penalties.

Memory trick: Breath or Blood, your choice is good, unless drugs are understood.
