Gov. Tom Wolf signed legislation this week to increase penalties for motorists who have multiple DUI convictions to try to end what critics call Pennsylvania’s “revolving door” for the most serious drunken drivers. The state Senate passed the final version last week after a couple of attempts to get the bill through the Legislature. The new law takes effect in November and increases penalties for some offenders who receive a third or subsequent DUI conviction. It aims to lengthen sentences by requiring someone convicted of a third DUI offense to serve consecutive sentences for separate counts, instead of serving the sentences at the same time.
