Although few people are foolish or sick enough to accumulate their 3rd DUI conviction within 5 years, Pennsylvania law provides for a mandatory driving license revocation for 5 years wihout appeal or any avenue for early reinstatement.
A 5 year driving suspension has a life altering impact. Any individual convicted of 2 DUI offenses within 5 years might be well advised to purchase an ignition interlock system for long term use.
