Ch. 1 · Common Conduct

While traveling through a section with a "slippery" warning sign, the road surface was not actually wet, so you ignored the sign and drove at normal speed, but since warning signs have no penalty provisions, this is not a violation.

[True / False · Hard]

Answer: ✕ False

Explanation

Warning signs themselves have no direct penalty provisions, but if you ignore the hazard indicated by the sign and cause an accident, you may be charged with violations such as failure to exercise safe driving practices. Furthermore, warning signs give advance notice of hazards, and even if the road surface is not wet at that moment, they indicate locations that become slippery in rainy or freezing conditions. The idea that "you can ignore it because there's no penalty" is incorrect.

The road wasn't even wet, and warning signs don't have penalties anyway, so ignoring it should be fine, right?

That's false. Warning signs might not punish you directly, but if you ignore the hazard and cause an accident, you can be charged with unsafe driving—and 'slippery' means it gets slippery in rain or frost, not necessarily right now.

Wait, so the sign is warning me about what could happen, not just what's happening this second?

Exactly. Never think 'no penalty' means 'no problem'—the hazard is real even if it's not visible yet.
