A standing passenger fell and was injured. The sudden emergency is treated as one of the circumstances in judging whether Sean's choice to swerve was reasonable.

Common questions
Frequently Asked
4
Does a sudden emergency automatically excuse a defendant's conduct?+
No. The emergency is simply one circumstance that shapes what counts as reasonable care. A jury still evaluates whether the response fell within the range of choices a reasonably prudent person might make under the pressure of the moment.
Can prior negligence that created the emergency still produce liability?+
Yes. Reasonable conduct after the emergency arises does not erase liability for earlier tortious conduct that produced the emergency conditions. The two inquiries remain separate.
How does the doctrine apply when judging a plaintiff's contributory negligence?+
The same principle applies. The fact that the plaintiff faced a sudden emergency requiring rapid decision is one factor in determining whether the plaintiff's conduct was reasonable.
Does the doctrine create a separate emergency standard of care?+
No. It does not replace the reasonable-person standard. The emergency is merely one of the circumstances that define what a reasonably prudent person would do.
