Turning from a Slip Lane
When entering a slip lane, turn on your left signal, check your rear-view and left mirrors, and do a shoulder check. Once you determine that it's safe to enter, scan your surroundings for pedestrians. Once on the lane, look out for oncoming vehicles and give way if necessary. A give-way sign is usually present. You don't need to turn on your right signal when exiting; just go ahead if the road is clear.
Practice makes perfect when it comes to merging or changing lanes. Always remain alert and check your mirrors. Additionally, do a shoulder check each time you switch lanes.
