Many foreign friends have driven for over a decade in their own countries and have solid skills, yet they feel a bit lost the moment they self-drive in China: why so many lanes at toll stations, tunnels one after another, the long western downhills looking intimidating, and cars merging one after another on the ramps. In fact, China's highway construction is of a high standard, with good surfaces, clear signs, and dense service areas, but a few specific scenes genuinely differ from driving habits abroad and need dedicated adaptation. Over the years I've run highways with drivers from many countries, and today, as an experienced hand, I'll describe in concrete terms the three scenes where foreign drivers tend to have problems, ramps, tunnels, and long downhills, along with the related highway rules, so you know what to expect from the start.
A general reminder first: in China you drive on the right. If you normally drive a right-hand-drive car and are used to keeping left, the first thing is to reset your sense of direction, and at junctions, ramps, and roundabouts especially, slow down a beat and think it through. Right-hand-drive cars are accepted at every port in China, with the same procedures and fees as left-hand-drive cars and no extra charge, but adapting your driving habits is up to you, so don't take it lightly.
1. Ramps: the first hurdle entering and leaving the highway
The ramp is the connecting section between the highway and ordinary roads, and also a high-accident spot, with the core issues being "speed difference" and "merging."
First, entering the highway. You come onto the ramp from a toll station or an ordinary road, and the ramp is often curved with a speed-limit sign, so follow the ramp limit rather than taking the bend at main-road speed. At the end of the ramp is the acceleration lane, whose job is to let you bring your speed up to match the main-road traffic before finding a gap to merge. A common mistake for newcomers (including foreign drivers) is merging slowly on the acceleration lane. Main-road cars are fast, and a large speed difference leaves following traffic no time to react, which is very dangerous. The right way is to accelerate decisively on the acceleration lane, signal, check the mirror and blind spot, and merge smoothly once a safe gap is confirmed, rather than cutting across abruptly.
Next, exiting the highway. Read the signs early and move to the right lane in advance, rather than braking hard and forcing a lane change at the exit. Once in the deceleration lane, slow down and take the ramp within the limit to leave the highway. Chinese highway exit signs usually start prompting several kilometers ahead, so build the habit of reading signs and planning early. If you miss an exit, keep driving to the next one and loop back; never reverse, drive the wrong way, or stop on the highway, which are extremely dangerous violations.
A separate word on toll stations. Many Chinese highway sections charge tolls, and stations have various lanes, with ETC electronic non-stop collection now widely used. Which lane a foreign or temporary-entry vehicle should take and how to pay follow the on-site instructions and your actual arrangement. If unsure, use a staffed lane rather than forcing the ETC. Slow down before the station, choose a lane by the markings, and note the signals and height and width limits above the lanes.
2. Tunnels: many rules, the key is preparing ahead
China is mountainous, especially in the southwest and northwest, where tunnels are numerous and long, some running several kilometers or even over ten. Tunnel driving has its own set of rules.
Before entering, first slow down. Tunnel mouths have speed limits, and moving from bright light into the tunnel brings a brief "dark adaptation" in which the eyes can't see clearly, so reduce speed early. Second, switch on the lights. Turn on the headlights (low beam) before entering, both to see and to be seen; this is mandatory, so don't rely on the tunnel lighting and skip it. Third, keep distance. Vision and braking judgment are affected inside, so open the gap and follow the indicated safe distance rather than sitting close to a large vehicle.
Inside the tunnel, note a few points: don't change lanes or overtake freely, as many tunnels have solid lines and cameras, so stay in your lane. Don't honk or use high beam, which dazzles the car ahead and oncoming traffic in a two-way tunnel. Mind crosswinds, light changes, and the road surface; some long tunnels have connecting sections in the middle where light and wind suddenly change, so hold the wheel steady. If a breakdown or accident happens in a tunnel, try to stop in the emergency parking bay, move people at once to the safety or escape passage inside, and call the police for help; never stay in the lane. Long tunnels generally have emergency passages, emergency phones, and fire equipment at intervals, so notice the signs in normal driving.
Exiting also matters. There's "light adaptation," where bright light suddenly causes momentary glare, so hold the wheel and keep the lane rather than turning in panic. Mind the crosswind at the exit, as tunnel mouths on valley bridges can be very windy, especially for tall off-road vehicles and RVs, so keep a firm grip.
Another detail: in long tunnel groups the speed limit can change repeatedly and there are many electronic speed checks, so watch the signs and your speed throughout rather than relying on feel.
3. Long downhills: the major feature of western self-driving
If you travel through the mountainous regions of Yunnan, Sichuan, Tibet, and Xinjiang, you'll meet continuous downhills of dozens of kilometers, a real test of the vehicle and driving skill, with the core risk being brake overheating, fade, and even failure.
A crucial rule: don't keep the brake pressed all the way down. Long braking makes the pads and discs heat up sharply through friction, and once the temperature is high enough, braking force fades noticeably, and in an extreme case the brakes fail, which is life-threatening on a long downhill. The right way is to use the engine's holding force, known as engine braking.
How to do it: in an automatic, don't stay in D on the downhill; shift to a low gear (L, M, or a low gear in manual mode, labeled differently across models) and let the engine hold the speed. In a manual, select a low gear and control speed with the gear. That way you don't brake the whole time, the speed is limited by the engine, and the brakes are used only for further slowing with pulse braking, pressing and releasing, rather than holding them.
Also watch the dashboard brake and temperature warnings closely. Some cars have a brake-temperature alarm, and trucks have dedicated water-spray gear (not usually needed for a passenger car). If the brakes feel soft, the pedal goes deep, or stopping distances lengthen, they may be overheated, so find a safe spot or emergency bay as soon as possible and let them cool naturally; don't pour water directly on red-hot discs, which can warp them.
Long downhill sections also have a life-saving feature called an escape ramp, usually on the right of a steep slope, an uphill dedicated track covered in loose gravel, made for a brake-failed vehicle to run into and stop. Notice its signs in normal driving, and if the brakes really fail, stay calm, pick the escape ramp, and drive in decisively while using the gears and every means to slow.
On long downhills also remember: don't sit close to large vehicles, as loaded trucks are themselves fighting brake fade downhill, so keep away to leave yourself room; control speed rather than rolling faster and faster, slow before bends, and a long downhill linked to curves is dangerous at too high a speed.
4. Other common highway rules to remember together
Beyond these three scenes, there are a few more points foreign drivers need to adapt to on Chinese highways.
Speed limits: Chinese highways limit by lane and vehicle type, with many signs and dense electronic checks, so follow the signs strictly and don't speed. Limits can be adjusted temporarily for weather and road conditions, so watch the electronic screens.
Lanes: the left is the fast/overtaking lane and the right is the slow lane, with large trucks mostly on the right. Don't occupy the fast lane at a crawl for long, and don't weave through frequent lane changes. Signal early, check the mirror and blind spot when changing.
Distance: keep enough gap, and double it in rain and fog. With heavy traffic in China, sitting too close leaves no room to brake in an emergency.
Large vehicles: there are many trucks and container cars, and big vehicles have blind spots, so don't stay alongside them for long; either overtake quickly or open the gap, and when overtaking signal fully and complete it decisively.
Weather: fog, rain, and patchy fog are common on some sections, and when visibility drops, slow at once, switch on lights (fog lights and hazards if needed), and open the gap; in serious conditions pull into the nearest service area to wait it out rather than pushing through.
Fatigue and rest: there are service areas at intervals, so rest in one when tired and don't drive fatigued; on long trips especially, share driving or ensure sleep.
5. A dedicated note for right-hand-drive and keep-left drivers
If you bring a right-hand-drive car from a keep-left country or region, beyond the steering position, what you really need to practice is the "mirror image" judgment: overtaking direction, roundabout flow, mirror and blind-spot habits, and which line to take through turns are all reversed. In the first few days after entry slow down, consciously remind yourself to keep right, and think through complex junctions and ramps before moving, returning to normal driving once new muscle memory forms. Keeping right in China takes adaptation, but it isn't hard once adapted.
6. How it connects with your entry procedures
These driving points are about "how to drive," while being able to drive legally on Chinese highways requires complete paperwork. A foreign vehicle entering temporarily carries a temporary plate valid for 3 months, and you hold the corresponding temporary driving permit. These must be handled, guaranteed, and declared uniformly by a travel agency with outbound qualifications; individuals can't clear customs themselves. Vehicle insurance is arranged for you before entry at the actual cost, so you're covered if something happens on the road. Focus on adapting to the roads and leave the paperwork and compliance to us.
7. A few honest words
Chinese highways are generally easy to drive, and what really needs dedicated adaptation is the speed matching on ramps, the tunnel rules, and brake control on long downhills, plus the sense of direction for keeping right. Master these, together with not speeding, avoiding fatigue, keeping distance, and staying clear of large vehicles, and you can steadily enjoy these world-class road landscapes.
