Danger Zones

In Traveller, there are Travel Zones and other Danger Zones. Either TAS warnings, or Imperial Navy or Scout Service Interdiction. And you can have either an Amber Zone which means to be cautious, or a Red Zone, which should be avoided and would be illegal to enter.

These are the different things that can cause an Amber Zone or Red Zone.

1.) Dangerous Wildlife

2.) War Zone or Violent Conflict

3.) Destructive Environment (aka Hellworld)

4.) Violent Crime or Law Level Extremes

5.) Immature, Xenophobic, or Indignant Culture

6.) Hazardous Atmosphere
