How many seconds after turning on the turn signal can you change lanes?

Changing direction should only be done after three seconds. You must use your turn signal when changing lanes, otherwise you will be fined for violating traffic rules. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," failure to use lights as required will result in a fine and a deduction of 1 point from your driver's license. Observe the rearview mirror of the intended lane: Check the traffic conditions in the lane you intend to change to, so you can react immediately in case of any sudden situations. Remember to use your turn signal: Turning on the signal before changing lanes alerts vehicles behind you. After signaling, wait a few seconds, confirm it's safe, then gently steer to change lanes. Avoid jerking the steering wheel when changing lanes. Change lanes at as small an angle as possible: Try to keep your vehicle parallel to the direction of travel and change lanes at a relatively small angle.
I've been driving for nearly twenty years, so I'm very familiar with signaling before changing lanes. Generally, you should wait 3 to 5 seconds after signaling before making your move. This gives the driver behind you enough time to react. Don't underestimate those few seconds—sometimes changing lanes in less than 2 seconds doesn't give them enough time to slow down, which can lead to a rear-end collision. I always count "one-thousand-one, one-thousand-two" to ensure a full 3 seconds. On highways, it's even stricter—you need to check the distance, and about 100 feet is safe. And don't forget to check your blind spot! I used to be too hasty and almost hit a motorcycle once. Now, I take it slower—safety is far more important than saving time. In rain or fog, wait an extra second. In short, developing good habits makes driving much easier and safer.
I'm a new driver who just got my license, and my instructor repeatedly emphasized the lane-changing rules. He said after turning on the turn signal, you must wait at least 3 seconds before changing lanes to let the cars behind clearly see the signal. During practice, I count the seconds by silently saying "one, two, three" as soon as I turn on the signal. Sometimes, when I'm nervous, I count too quickly, and my instructor reminds me to relax. Not waiting long enough can be dangerous, especially in crowded areas where cars behind might honk or brake suddenly if you don't wait. I also learned a trick: first turn on the signal, then check the rearview mirror and blind spots to confirm no cars are approaching before changing lanes. Sticking to this sequence helps reduce mistakes. New drivers tend to be impatient, but I'm gradually improving by reminding myself every time I drive to stay calm and prioritize safety above all else.
