When entering a highway, you need to first turn on the left turn signal. While in the ramp, accelerate to over 60km/h, then pay attention to the traffic on the highway before gradually steering into the main lane. After exiting the highway, turn on the right turn signal and reduce your speed to 40km/h when entering the ramp. Precautions for driving on highways are as follows: Observe speed limit signs: Drive within the prescribed speed limits. Do not exceed the maximum speed limit and ensure you are in the correct lane for your speed. Additionally, speed limits on highways are segmented, requiring drivers to be particularly attentive to speed limit signs. Avoid sudden braking on highways: This prevents rear-end collisions caused by vehicles behind not braking in time, and even more severe multi-vehicle collisions. Stay focused while driving: Be mindful of guardrails to avoid scraping or even colliding with them due to insufficient safety distance or momentary distraction. Highways have wide lanes that can accommodate multiple vehicles simultaneously, so it's advisable to stay away from guardrails unless necessary.

I've been driving trucks for twenty years, often on long-haul routes. When entering the highway, you must signal left in advance because you need to merge from the ramp onto the left main lane. Never wait until the last moment to signal—other drivers won't have time to react. Especially for us in large vehicles with big blind spots, signaling at least five seconds early is the safest approach. Also, a reminder for new drivers: accelerate to at least 60 km/h before merging onto the highway, or you'll struggle to keep up with the fast-moving traffic in the main lanes. Always check your left mirror and blind spot, leaving at least a three-car-length safety gap. Once, I saw a car that didn't signal and forced its way into the lane get rear-ended—scattering parts everywhere.

Last week, my cousin just got his driver's license, and I took him to practice on the highway. I pointed at the ramp entrance and said, 'Watch carefully, now is the time to turn on the left turn signal.' He asked why it wasn't the right turn, and I explained that the main highway lanes are on the left, so you need to merge left. This kid kept forgetting to signal during practice, so I made him repeat 'left signal - rearview mirror - accelerate' three steps before entering the ramp. Actually, it's not just when entering the highway; you also need to signal left when merging back from a service area. I've noticed that the most dangerous thing for beginners is hesitation—either not signaling and forcing their way in or signaling but not daring to accelerate. Remember: turn signals are your language; use them early to communicate your intentions.

Yesterday, while driving my daughter to college on the highway, she suddenly asked from the passenger seat: 'Mom, why are we turning on the left turn signal?' I explained while driving: 'The highway has a one-way traffic structure, and the main lane is always to the left of the ramp. Turning on the left signal tells the cars behind us, "I'm moving to the left." For family cars like ours, it's best to signal at least 200 meters in advance. Don't imitate some cars that wait until they're right next to the main lane to suddenly turn the wheel. I usually pay attention to the navigation prompts. When I hear the voice say, "Enter the highway in 500 meters," I start preparing to signal. I also check the dashboard to make sure there are no turn signal failure warnings, so the signal isn't wasted.'

I've worked in an auto repair shop for ten years, and the most common complaint I hear from car owners is about turn signal malfunctions. Many beginners get confused about the rule of using the left turn signal when entering a highway. Actually, just remember three key points: First, look for the blue directional sign with an arrow pointing left. Second, keep the signal on for at least three seconds. Third, don't fixate on the steering wheel; focus more on observing the road conditions behind you to the left. If it's raining, clean the light cover in advance, as water reflections can reduce the visibility of the signal. Also, note that some older cars with retrofitted turn signals might flash too quickly, which could cause following vehicles to misjudge the distance.

Last year, I drove 2,000 kilometers on highways during a road trip, which deeply impressed upon me the importance of proper turn signal usage. Before entering each highway ramp, I would activate the left turn signal in advance while glancing at the center rearview mirror to assess traffic flow. If I spotted a large truck approaching from behind, I preferred to slow down and yield rather than force my way in. Here's a handy tip: when signaling with your left hand, lightly rest your right hand on the steering wheel to prevent unintentional vehicle drift caused by nervousness. During daytime with strong sunlight, I make a point to verify the blinking shadow of the turn signal projected on the ground, ensuring clear signal transmission. Extra caution is needed at night - turn signals become lifesaving indicators in low-light conditions.
