Notes

Not yet verified against the state's official statutes.
Pennsylvania grades the offence by tier: 0.08% to under 0.10% (general impairment), 0.10% to under 0.16% (high rate) and 0.16% or higher (highest rate), measured within two hours of driving. Driving while incapable of safe driving is an offence at any concentration.
The statute says 'minor'; its definition was not read for this entry. A first offence is penalised under the higher tier of section 3804(b).
For a school bus or school vehicle the limit is 0.02% or greater.

These rules are set at national level in the United States and apply here too, alongside the rules above. All national rules for the United States
