How to make left and right turns on an overpass in Subject 4?
4 Answers
Subject 4 overpass left turn method: When making a left turn, you must drive past the overpass before turning; you cannot turn left directly. First, turn on the right turn signal, then after crossing the bridge, make one right turn followed by another left turn or two right turns to achieve the left turn. Subject 4 overpass right turn method: Make a right turn before crossing the bridge. Subject 4, also known as Subject 4 theoretical test or driver theory test, is part of the motor vehicle driver's license assessment. The violations examined in Subject 4 include: talking on the phone while driving, not wearing a seatbelt, speeding, covering the license plate, running a red light, not following the guide arrows, and using the emergency lane.
I just passed the fourth subject of the driving test, and there are actually tricks to turning on an overpass. Right turns are the simplest—just spot the exit sign early, switch to the far-right lane, and follow the ramp down. Left turns require a detour. Remember the rhyme: 'For a left turn, go straight first, then turn right after crossing the bridge.' For example, at a cloverleaf interchange, you’d first drive straight past the underpass, spot the right-turn ramp sign, turn right onto it, and loop halfway around to merge onto the left-side road. The dashed arrows on the test diagram hint at this detour route. The worst mistake is missing the signs and turning too early, so I always start checking the signs 200 meters ahead when approaching an overpass.
As someone who drives long distances every day, I want to say that when turning on an overpass, just follow the arrows on the ground. For a right turn, directly cut into the ramp to exit the bridge, but be cautious of sudden appearances of non-motorized vehicles. For a left turn, you must cross the entire bridge and find the right-turn ramp on the opposite side to detour. For example, on a roundabout-style overpass, a left turn requires spiraling up like drawing a semicircle, turning 270 degrees. The key is not to rely on intuition—go straight when you should, and only merge after crossing the bridge when you see the 'Left Turn Lane' sign. Yesterday, I encountered a novice driver trying to take a shortcut for a left turn on a cloverleaf interchange and ended up going the wrong way—how dangerous!
Our driving school instructor teaches in a straightforward manner: For a right turn on the overpass, take the rightmost gap; for a left turn, treat it as two right turns. First, go straight through the bridge to find the right-turn ramp, then make a right turn and loop halfway around—naturally, you'll end up on the left side. The dashed-circle routes in the test diagrams are dedicated left-turn lanes. In practice, slow down in advance; the speed limit in bridge areas is 40—don't exceed it. Pay attention to the blue-background, white-letter signs. Once, a student missed the ramp by rushing a yellow light and had to detour three kilometers before making a U-turn back.
