What is the minimum duration for a license suspension if a motorist refuses to take a chemical test after being arrested for DUI?

The minimum duration for a license suspension when a motorist refuses to take a chemical test after a DUI arrest is indeed one year. This is in line with Pennsylvania's implied consent laws, which stipulate that all drivers implicitly agree to submit to chemical testing when they operate a vehicle. If a driver refuses to comply with this requirement, the consequences include an automatic suspension of driving privileges.

This one-year suspension serves as a deterrent to discourage individuals from declining such tests, as refusal can indicate a driver's consciousness of guilt regarding alcohol or drug use. Moreover, the timeline is explicitly defined in state law, which helps ensure uniformity in enforcement across different jurisdictions.

The longer durations associated with the other choices, such as two years or an indefinite suspension, typically apply to more severe circumstances or repeat offenses and are not the standard for a first refusal. Hence, one year is the correct and established minimum for this specific scenario.
