6.5 Driving Etiquette & Road-User Awareness
Key Takeaways
Driving etiquette and awareness (มารยาทและจิตสำนึก) is one of the four subjects in the DLT's 5-hour training course.
A good driver shows patience, forgiveness, and responsibility, and most crashes are caused by drivers rather than vehicles or roads.
Section 43(8) of the Land Traffic Act bans driving without regard for others' safety, and since 2022 this carries up to 1 year in prison or a fine of 5,000 to 20,000 THB.
Section 14 allows the horn only when necessary or to prevent an accident, and forbids long or repeated blasts.
On a narrow road where two vehicles cannot pass, section 39 requires the larger vehicle to stop at the left edge and let the smaller one through.
6.5 Driving Etiquette & Road-User Awareness (มารยาทและจิตสำนึก)
Quick Answer: Driving etiquette and awareness (มารยาทและจิตสำนึกในการขับรถ) is one of the four subjects in the DLT's 5-hour training course and one of the DLT practice-test categories. Most crashes come from driver behaviour, so the DLT wants drivers who show patience, forgiveness, and responsibility. Several etiquette rules are also law. Section 43(8) bans driving without regard for the safety or trouble of others. Section 14 allows the horn only when necessary. Section 49 requires letting faster vehicles pass. Section 39 requires the larger vehicle to wait on a narrow road. Section 32 requires special care for children, older people, and people with disabilities.
Good manners on the road are not just politeness. Many of the DLT test's etiquette questions describe behaviour that is also an offence.
1. The Qualities of a Good Driver
A typical DLT question asks which qualities a good driver should have. The answer is all of them: patience and self-control, willingness to forgive other people's mistakes, and responsibility for everyone's safety. Another asks what causes most crashes. The answer is the driver, not the vehicle, the road, or the weather.
In practice this means:
- Patience: Accept that traffic will sometimes be slow. Do not force your way through.
- Forgiveness: When someone makes a mistake, give them room instead of punishing them.
- Responsibility: Never drive drunk, drowsy, or distracted. Keep your vehicle roadworthy and your licence, tax, and insurance current.
2. Etiquette Rules That Are Also Law
| Behaviour | Legal Basis | What It Means in Practice |
|---|---|---|
| Considering others' safety and trouble | Section 43(8) | Since 2022, driving without regard for others' safety can mean up to 1 year in prison or a fine of 5,000–20,000 THB, and costs 4 demerit points |
| Using the horn only when necessary | Section 14 | Use the horn to warn of danger, not to hurry people. No long or repeated blasts |
| Letting faster traffic pass | Section 49 | When signalled, signal back, slow down, and keep left |
| Narrow roads | Section 39 | Where two vehicles cannot pass safely, the larger vehicle stops at the left edge and lets the smaller one through |
| Protecting vulnerable road users | Section 32 | Take special care near children, older people, and people with disabilities, and warn pedestrians when needed |
| Not blocking junctions | Section 71(3) | Do not enter a junction or yellow box if you cannot get out the other side |
| Leaving a driveway | Section 74 | Stop and let traffic on the road go first |
| No careless or dangerous driving | Section 43(4) | No tailgating, brake-checking, or weaving |
3. Everyday Courtesy on Thai Roads
These situations come up often in DLT etiquette questions:
- Letting cars out of a soi in heavy traffic: Leave a gap and let some vehicles out, taking turns with the through traffic. Do not sound the horn or block the soi mouth.
- Keeping the junction and yellow box clear even when your light is green, so cross traffic can move.
- No queue-jumping: Do not use the shoulder or a turn lane to cut in at the front of a queue, for example at a bridge approach or a soi entrance.
- U-turn only at proper U-turn points, even if the nearest one is far away. Do not U-turn across traffic where it blocks both directions.
- Stay in the correct lane: Do not use a left-turn, right-turn, or U-turn lane to get ahead when you are going straight.
- Park considerately: Never double park, never block a driveway, and never use a disabled bay unless entitled to.
- Dip your headlights for oncoming traffic, and do not dazzle the driver in front (7.2).
- Drive slowly through communities, markets, and school zones, and use the horn only when there is danger.
4. Staying Calm: Road Rage
Aggressive driving turns small conflicts into serious crashes.
- Do not retaliate. If another driver cuts you off, flashes you, or sounds the horn, let it go and increase your distance.
- Never brake-check a tailgater. Move left and let them pass when it is safe.
- Avoid eye contact and gestures with an angry driver. If someone follows or threatens you, drive to a busy public place or a police station and call 191.
- Know the Thai headlight flash: In Thailand, a driver flashing their headlights usually means "I am coming through", not "you go first" (7.2). Never pull out on a flash without being sure.
5. Awareness of Other Road Users
- Motorcyclists make up most of Thailand's road deaths. Check mirrors and blind spots, signal early, and leave space (6.2).
- Pedestrians have to cross where there is no crossing on many roads. Slow down near markets, bus stops, and schools, and stop for anyone on a crossing.
- Cyclists and street vendors' carts move slowly. Pass only with plenty of room.
- Emergency vehicles: Stop close to the left edge, never in a junction (section 76).
- Buses and trucks need more room to turn and stop. Do not cut in front of them.
6. Awareness of Yourself
The DLT's awareness (จิตสำนึก) training asks drivers to be honest about their own condition:
- Tired? Stop and rest. Driving while unfit breaks section 43(1).
- Been drinking? Don't drive. Novice drivers have a 20 mg% limit (1.2).
- Upset or in a hurry? Leave earlier, and remember that arriving a few minutes late is better than not arriving.
- Unsure of the route? Plan it before you set off, or pull over to check directions.
DLT Theory Test Traps
- "All of the above" is usually right when the options list good-driver qualities.
- The horn is a warning device, not a way to express impatience (section 14).
- Courtesy never overrides safety: Do not wave a pedestrian or another driver across in front of traffic you cannot control.
In heavy traffic, several cars are waiting to come out of a soi onto your road. What is the courteous and correct thing to do?
Sound the horn so they know not to pull out
Leave a gap and let some of them out, taking turns with the through traffic
Stop across the soi entrance so no one can cut in
Speed up to close any gap in front of you
Which qualities should a good driver have?
Patience and self-control
Willingness to forgive other people's mistakes
A sense of responsibility for everyone's safety
All of the above
Under section 14 of the Land Traffic Act, when may a driver use the horn?
Only when necessary or to prevent an accident, without long or repeated blasts
Whenever the vehicle ahead is slow to move off at a green light
To greet friends or other drivers
At every junction, to announce that you are coming
Sections you finish are checked off in the contents.
