Warning signs
Yield sign ahead
Standard MUTCD design · not an official government site
What it means
This sign warns that a yield sign controls the junction or merge within a short distance, typically where the actual sign is hidden by a curve or where approach speeds are high. Seeing the inverted triangle symbol in advance lets you plan the scan-and-give-way sequence before you arrive, rather than conducting it at the last moment. The warning buys you real distance: used properly, the entire approach becomes preparation time, and you reach the actual yield sign with your mirrors already checked, your speed already settled and your gaps already identified.
How it gets misread
Drivers sometimes confuse the warning with the instruction itself and stop unnecessarily at the warning sign location. The opposite error is treating the warning as optional and arriving at the real yield sign with no scan already made.
What to do
Use the approach distance to do the yield work early: check mirrors, look along the road you will join, and identify the gaps you could use. Then reach the yield sign prepared either to continue into a gap or to stop cleanly. Never stop at the warning sign itself; the obligation exists where the actual sign stands.
