The Ministry of Transport is going to increase the maximum speed for passenger cars on a number of highways from 90 to 120 km. The measure is expected to be published in the Royal Gazette in early April.

Eligible roads must meet a number of requirements:

  • at least four lanes
  • a guardrail in the middle
  • a straight road without curves and U-turns

The speed limit in the right lane is 100 km. When approaching a U-turn or bend, the maximum speed is 60 km.

New traffic signs will be installed stating the speed limits and a 60 km sign on the approach to a junction or U-turn. In residential areas and near schools, a maximum speed of 30 km per hour applies.

There may also be an adjustment of speed limits for trucks.

    That lower speed limit for the right lane – shouldn't that be the left lane? Seems more logical to me!

    • Rob V says up

      This is a well-known case of 'journalist does not ask questions but knows a good quote about it'. The 100 km/h restriction is for the rightmost lane if there is a U-turn, without a U turn it is 4 km/h on all 120+ lanes. However, a U turn in the median strip with speeds of 120 or 200 km does not seem very wise to me… If I were a journalist, I would ask further questions.

      The whole quote: “The areas where cars would be allowed to legally reach 120kph must at least have four traffic lanes with median barriers and the road must be straight, without junctions or U-turns, he said. In that case, the minimum speed for the right lane would have to be 100kph to prevent crashes, he said.”

    That motorway in the photo seems ideal to me for a different, higher speed. The chance that you will encounter a tuk-tuk, a moped or a walker with a dog on that road on the left lane is indeed present (because this is Thailand…), but is smaller there than with normal highways.
    But whether the Thai will care about speed limits at junctions? The Thai don't care about anything. Well, we'll see from the statistics in a few years.

    A bit confusing entry:

    a straight road without curves and U-turns.
    Most straight roads do not have bends.

    a straight road without curves and U-turns
    and on approach to a junction or U-turn a 60 km sign

    The speed limit in the right lane is 100 km.
    That will probably be the left lane, as Thailand drives on the left.

    I assume that the text “New traffic signs will be placed…” has nothing to do with those highways anymore, or maybe it has been since “A speed limit applies to the right lane”

    But I fear that the number of deaths in traffic will continue to rise.

      Have you ever driven in Thailand?

      A U-turn is on the right lane, it's a kind of headland on the highway. It moves from right lane to right lane.
      Highways sometimes also run right through towns and cities. Take the 1 from Bangkok north. It crosses many built-up areas.

  4. RonnyLatYa says up

    Isn't it at least 100 on the right lane instead of maximum 100
    “The speed limit for vehicles traveling in the furthest right lane is no less than 100kph.”

    • Rob V says up

      Minimum, maximum.. what's the difference? I do what I want anyway. All joking aside, I hadn't read it correctly either by projecting a single central reservation U turn in my mind, while modern roads often neatly have an unlevel U turn.

  5. Bert says up

    Because overtaking on the left is allowed in Thailand, the right lane will have to reduce speed when approaching a U-turn. If all goes well ( 🙂 ) they have already pre-sorted to take the u-turn. Also with insertion one uses the right lane.

    • Mart says up

      Dear Bert,
      I would like to hear from you where you read that overtaking on the left is allowed, because it is NOT. If you take the U-turn, it is much wiser to first cross over to the left lane and not to merge into the right fast lane. Therefore, the use of u-turn is life-threatening and cause many accidents.
      Wish you good health and happiness.
      Kind regards, Mart

      • Rob V says up

        Mart, that is stated in the traffic law: overtaking on the left is allowed if there are 2 or more lanes in the same direction. Or when a vehicle wants to turn right. In all other cases it is not allowed. Then you just overtake on the right.

        “Section 45 (400-1000B)
        [No driver shall take over another vehicle from the left-side unless:
        a. the vehicle to be overtaken is making a right turn or has given a signal that he is going to make a right turn
        b. the roadway is arranged with two or more traffic lanes in the same direction.]”

    Unfortunately, every Thai thinks of himself as a good driver.

    In Flanders it is said that “you must have your eyes on your ass” when you are driving in Thailand.
    Can someone explain to me the cause of Thai driving skills?

    They may have the honor of being one of the deadliest countries in traffic. Why isn't the government taking stricter action here? Then we will not talk about the state of many vehicles, it is scandalous what is driving around on the roads here. And the more noise my vehicle produces the happier I am 🙁

  7. Martin Farang says up

    This is good news!
    Most intersections already drive faster than the allowed speed. Now with the motorcycle on the toll roads and we will get there.
    Can flut Rutte take an example! Increasing the permitted speed.

  8. janbeute says up

    Incidentally, nothing new under the sun, many Thais already drive at that maximum speed and not only on 4 lane roads with or without bends and U turns.
    Yes, after all, you have to do something to stay first in the world ranking of fatal traffic accidents.

    A U turn can be on the right side where you end up on the other way. Dangerous to life as the average road user cannot anticipate the pre-sorting. They also often remain on the 2nd lane and thus block through traffic. They also usually do not know how to indicate direction.
    The other U turn which is much safer is the one under the bridge. Unfortunately, you don't always have this option.

    Increasing speed as long as nothing is done about driving skills results in more deaths.
    You regularly notice that they are so close to you (this is called tailgating) that you are forced to turn on the warning lights. They then pass left or right with a black cloud from the exhaust and then have to hit the brakes again because the traffic on the road requires this.
    The dangerous drivers are often the kerry vans, thailand post and often work traffic.
    Even as crazy as it is, there is a characteristic behavior in it: BMW drivers do worse in terms of antisocial behavior as well as many new motorists with a red license plate (new car)
    As long as no changes are made to driving behaviour, the number of accidents will increase.
    Another addition, but that more or less applies to built-up areas that stop at a red light. You often see that a number of cars are quickly driven through the red light. So if you drive away from green, you still have to watch out.
    You need eyes in front and behind and left and right. Participating the Thai way is therefore the best..

    • Pieter says up

      What you should not forget is that you should not drive with the Dutch mentality in Thailand. In the Netherlands we own our place on the road. If someone threatens to merge right in front of us, we close the gap. If you just want to overtake at the maximum speed and someone comes driving at (too) high speed, you throw him in front of it. Because yes, then you shouldn't drive too fast. And if someone gets too close to the bumper, we deliberately keep driving longer in front of him, because otherwise he will never learn.
      In Thailand, no one is really in a hurry. If you want to drive onto a main road, let your car drive very slowly onto the road, there is always someone who will stop. If someone else comes through the red, you just give a little less gas. And if someone is too close to your license plate, turn left and let them pass.
      And, in Thailand you have to drive defensively, otherwise you're screwed.
