When a vehicle enters the highway from the ramp, the left turn signal must be turned on. Below is relevant information about driving on the highway: 1. Reason for turning on the left turn signal: When entering the highway from the ramp, it is necessary to slow down, observe carefully, and turn on the left turn signal to alert vehicles already on the highway. After confirming that there is no hindrance to normal traffic, the vehicle can then enter the driving lane. 2. Speed requirements when entering the highway: The speed is generally required to be below 40km/h. Before entering the driving lane, the vehicle should quickly accelerate to over 60km/h, carefully observe the traffic conditions in the driving lane, and choose the right moment to enter the driving lane. The specific and accurate speed should comply with the speed limits indicated by the signs.

I've been driving for over a decade and always pay special attention to turn signal usage when merging from ramps onto highways. The correct procedure is: immediately activate the left turn signal after entering the acceleration lane of the ramp, signaling at least 3-5 seconds in advance to clearly communicate your merging intention to following vehicles. Don't rush to change lanes at this point - first check your mirrors to assess main lane traffic conditions, especially watching for large trucks approaching from the left rear. Only when your speed approaches that of highway traffic should you smoothly merge into an appropriate gap. Remember to keep the turn signal on until your vehicle is completely straightened in the main lane - turning it off too early might cause misjudgment by other drivers. The type of ramp matters too - for sharp-curving ramps, signal earlier and reduce speed to avoid fishtailing or loss of control. The essence of safe merging boils down to: early signaling, thorough observation, and proper speed matching.

Last week when I was driving back to my hometown, I almost had an accident at the highway entrance because of a reckless driver who didn't use turn signals. The correct procedure is actually quite simple: you should turn on the left turn signal the moment you enter the acceleration lane from the ramp, giving vehicles on the main road ample time to react. Using turn signals isn't just a formality—it's crucial to provide following vehicles with enough reaction time, ideally keeping the signal flashing for more than 5 seconds. My habit is to accelerate to around 70 km/h while on the ramp while keeping a close eye on the left rearview mirror to find a safe gap. Once during rainy weather with poor visibility, I deliberately activated my turn signal 10 seconds in advance and even flashed my high beams twice to alert the following vehicle. After merging onto the main road, don't forget to turn off the signal and take a moment to check the dashboard to ensure no warning lights are illuminated. Also, remember that lane changes are prohibited on solid lines at ramps—these details can truly be matters of life and death.

Last year when I was taking my driver's license test, the instructor repeatedly emphasized this: you must turn on the left turn signal when entering a highway ramp. I still remember the nervous scene of my first time on the highway—immediately turning on the signal after entering the acceleration lane, gripping the steering wheel tightly while checking the rearview mirror. There are three key points: signal early (don't wait until you're about to hit the guardrail), match your speed (don't block the acceleration lane by going too slow), and observe thoroughly (take a quick glance at the blind spot on the side and rear). Once when I was driving at night, I deliberately waited for the turn signal to flash six or seven times before changing lanes. After merging into the main road, I often notice new drivers forgetting to turn off their signals, which can mislead following drivers into thinking you're making consecutive lane changes. Remember, turn signals are tools for communicating with others—on the highway, speeds are high and reaction times are short, so make sure to use them properly.

I often drive long distances and frequently see people flustered when entering the highway from the ramp. The correct procedure is actually straightforward: turn on the left signal as soon as your car enters the acceleration lane on the ramp—don’t wait until you’re close to the main road to hit the switch. The key lies in the observation phase: I scan the left, center, and right rearview mirrors, paying special attention to the approaching speed of large trucks. If a vehicle in the mirror grows larger quickly, it means the other driver is speeding, so I delay merging. In rainy or foggy conditions, I signal much earlier, sometimes even rolling down the window to listen for tire noise to gauge distance. Never brake at the moment of merging—maintain throttle to match the speed of traffic. Remember to keep the turn signal on until the entire front of your car is in the travel lane; turning it off prematurely can easily cause a rear-end collision.
