Algonquin Road is a four lane, divided state thoroughfare with a speed limit set artificially low at 40, all the way west until you hit Quentin Road. The Rolling Meadows portion is accompanied by a large row of apartments, plus numerous businesses with entry/exit driveways. Cops patrol here regularly, as this area is notorious for DUI pullovers during the wee hours. West of Route 53, the road is under the jurisdiction of Schaumburg. The traffic flow here increases to about 50, but cops also stake this area out as well, with plenty of driveways and apartment complex entry-ways to sit in. This portion is also the site of various roadblocks that may occur near the holiday season.
