Here in Finland the main reason is this: Image source Road markings are used to denote speed limits but never as a primary mean. And as Jung Lee points out, re-applying road paint is labor intensive, especially here, as studded tyres usually erode most of the paint in one or two winters. Edit: The Finnish law actually states that road markings, such as ...

You read as you approach. Theoretically. In reality, levels of visual acuity mean that some people (like you and I) can read the whole block at once. Another reason that painting information on the pavement isn't always ideal. Here's a good visual for how this is designed to function in practice: The trick is (as the image above shows) the spacing of ...

I would say there are a couple of aspects here Line of sight : Though while driving your line of sight is mainly on the road, the main point of focus is at object ahead of you straight ahead (e.g. a vehicle going ahead). Hence writing the speed signs on the road would have to require the person driving to focus down and assimilate the information which ...

Besides the snow-covered roads—a very clear reason but only applicable in a small number of cases—there are several vision-related explanations. The first one is simply geometrical. On an empty road, a traffic sign remains for a long time close to the centre of the driver's field of view (where vision is sharpest) and can be seen from far away. It gets off ...

In complete agreement with the other answers, but to provide an alternate viewpoint: If you were driving at night, your headlights will reveal the beginning of the sentence before the end.

In addition to the ones mentioned by others, here are additional considerations: Road paint is more labor intensive to install initially. Road paint is more labor intensive to maintain as well because road needs to be repaved every few years and/or potholes filled. But more importantly, road paint is slippery in wet weather. (well known concerns among ...

Couple of reasons: When driving there are often cars ahead, so anything written on the road can be obscured. The same is true with street signs, but it's not nearly as bad. Drivers look forward and straight. Signs are usually off to either side of the road, where both a driver and passenger can see. Thus the signs are a little easier to view for all ...

Extreme Environmental Conditions Similar to conditions in Finland, as shown by @locationunknown, locations in India suffer problems as well. Where monsoon damages roads every year. Imagine speed limits and other markings on road would never be seen on these roads. Other constraints here in India, why speed limits are not on road is the sheer ...

I have bad vision. I can see well enough to drive, but if that message is more than a line or two, I won't be able to read the beginning of it before I've passed the end of it. They're written backwards for me.

Also, information printed on the road can only be read when there is little traffic, or at least no cars blocking it (or other obstacles such as weather as already previously stated). In rush hour, for example, your speed limit on the road would likely be missed by everyone. The same would happen even if you were driving at the speed limit and there was a ...

It facilitates reading the text in moderate traffic. If there are other vehicles on the road and you are following at a safe distance, you will read the closer text first as your view of the farther text will be blocked. This allows you to read the full message incrementally. Obviously this breaks down when there is no traffic and you have decent vision, ...

Apple's word isn't final when it comes to UI design, but they make it a point to talk about this in the iOS Human Interface Guidelines: As much as possible, avoid displaying a splash screen or other startup experience. It’s best when users can begin using your app immediately. The barrier to entry should be as low as possible for first-time users. ...

Where I live in Australia (a place very rarely affected by snow cover), speed limits are painted on the roads only when they change: Image from Teach Yourself Driving in Australia Regular speed limit signs are also posted both at the point where the limit changes and many times along a roadway as a simple reminder or for commuters that have joined a ...
