可能会发生不好的事情，让人受伤或死亡
Likely to cause harm — an icy road, a fast river, a job done carelessly. Chinese states it about the situation, not just the feeling: 这条路很危险 says the road itself is a hazard, not merely that walking it feels scary.

常见错误
不太对他一个人回家，他很危险。
正确他一个人回家，很危险。
危险 said of a person as subject means that person is a threat to others, not that they face a threat. To say someone is at risk, leave the situation itself as the subject — 一个人回家很危险 — rather than making the person the subject of 很危险.
