A common mistake is treating this sign like any other warning sign and not specifically preparing for the unique characteristics of jaunting cars, such as their slower speed or potential for unpredictable movement. Learners might also fail to reduce speed sufficiently in advance or forget to increase their observation for horse-related hazards.
You should be very cautious about overtaking when approaching an area indicated by the W-154 sign. Overtaking is prohibited if it compromises your ability to observe or react to the jaunting car hazard.

While the sign provides advance warning, the exact distance and severity of the hazard can vary.
