Obey all posted speed limits. But remember that they are for ideal road, weather and visibility conditions. You may need to drive below the posted limit in bad weather or when visibility is especially poor. Pull to the right (with care) and stop clearof intersections when you see or hear emergency vehicles. FREEWAYDWNG Mile for mile, freeways(also called thruways, parkways, expressways, turnpikes, or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway drivingis: Keep upwith traffic and keep to theright. Drive at the same speed most of the otherdrivers are driving. Too-fast or too-slow drivingbreaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. Entering the Freeway At the entrance thereis usually a ramp that leads thefreeway. If you to have a clearview of the freeway as you drive along the entrance ramp, you should begin to check traffic.Try to determinewhere you expect to blend with the flow. If traffic is light, you may have no problem. But if it is heavy, find a gap as you move along the entering lane and time your approach. Try to merge into thegap at close to the prevailing speed. 202
