How does negligence law treat physical disabilities such as blindness?

In the context of negligence law, the legal system generally evaluates conduct based on the standard of a hypothetical "reasonable person." While this standard is external and typically ignores individual traits like excitability or ignorance, the law does make specific allowances for physical disabilities, such as blindness.1

However, these allowances are balanced by a duty of care placed upon the disabled individual. The law demands that persons with physical disabilities avoid needlessly placing themselves in situations where their specific disability may cause harm to themselves or others. It is important to note that this consideration is generally limited to physical disabilities and does not extend to mental disabilities.1
