Yield sign

Welcome to our website. It is generaly simplier version of wikipedia. You will find there selected articles. Enjoy!

In road transport, a YIELD (Canada, Ireland, and the United States) or GIVE WAY (Hong Kong and most Commonwealth countries) traffic sign indicates that a vehicle driver must prepare to stop if necessary to let a driver on another approach proceed (but has no need to stop if his way is clear). A driver who stops has yielded his right of way to another. In contrast, a stop sign always requires a complete stop.

The first yield sign was installed in Tulsa, Oklahoma, having been devised and designed by Tulsan police officer Clinton Riggs. Riggs invented only the sign, not the rule, which was already in place. Despite Oklahoma being landlocked, it is sometimes suggested the rule was made by analogy to the International Regulations for Preventing Collisions at Sea. The sign as originally conceived by Officer Riggs was shaped like a keystone; later versions bore the shape of an inverted equilateral triangle which has been almost universally adopted. With the pole, the overall shape is that of the "Y" in YIELD, which has been noted mainly by teachers of the English language. Particular laws regarding appearance, installation, and compliance with yield or give-way signs vary by jurisdiction.

United States

In the Federal Highway Administration's Manual on Uniform Traffic Control Devices, a yield sign may be warranted:

1. On the approaches to a through street or highway where conditions are such that a stop is not always required.
2. At the second crossroad of a divided highway, where the median width at the intersection is 9 m or greater. In this case, a stop or yield sign may be installed at the entrance to the first roadway of a divided highway, and a yield sign may be installed at the entrance to the second roadway.
3. On a channelized turn lane that is separated from the adjacent travel lanes by an island, even if the adjacent lanes at the intersection are controlled by a highway traffic control signal or by a stop sign.
4. At an intersection where a special problem exists and where engineering judgment indicates the problem to be susceptible to correction by the use of the yield sign.
5. Facing the entering roadway for a merge-type movement if engineering judgment indicates that control is needed because acceleration geometry and/or sight distance is not adequate for merging traffic operation.

In many states traffic is allowed to turn right on a red light providing they first stop and must still then yield.

United Kingdom

By contrast, the United Kingdom's Road Traffic Act calls for GIVE WAY signs and road markings far more often at junctions (intersections) where stop signs would be used in the US. The mandatory road marking accompanying the sign consists of a large inverted triangle painted just before the place to give way..

In Wales the Give Way text is suplimented by Ildiwch above the English Give Way. Stop signs are relatively rare, but foreign drivers occasionally stop anyway because that is their habitual response at a junction. If a native driver behind them, seeing the way is clear, does not expect them to stop, a rear-end collision may result.

In the United Kingdom, a stop or give-way sign sign may be preceded by an inverted, blank, triangular sign with a subtitle plate saying, for example, "Give way 100 yards". In some other parts of Europe, the sign at the intersection itself is also blank.

Unlike intersections, Roundabouts require drivers only to yield, not to stop; in normal conditions traffic flows more freely. However, a left turn on red is not permitted; lane- and direction-specific traffic lights allow traffic to turn left while drivers wishing to go straight through the junction or turn right are held by a red light.

Republic of Ireland

In the Republic of Ireland, the sign reads "Yield" in most areas, though in Gaeltacht (Irish language-speaking) areas, it reads Geill Slí ("Give Way") instead. Signs erected before 1997 and still in situ read "Yield Right of Way" instead of simply "Yield". Use of the sign is similar to that of the UK "Give Way" sign.

Brazil

In Brazil, the "Yield" sign has the same shape and colors of the American sign, but with nothing written within. Brazilians know this sign and call it as "Dê a preferência" ("Give up the preference so the other can pass").
