Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Example: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Example solution: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Example explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

Problem: When driving on a US interstate highway, how will I know if an upcoming exit ramp will be followed by an entrance ramp to re-enter the highway after exiting? (e.g. if I need a gas station or food break)

In rural stretches re-entry is almost always possiblebut not always. In cities, especially where various freeways meet, I feel like re-entry is much less common. But how to know in advance without trial-and-error?

(When I started driving I had erroneously thought that if the exit says "Exit only" in yellow, there would be no return entrance, but I now believe this refers to the specific lane being forced to exit, which is really nothing to do with ability to re-enter after exiting.)
Solution: How can I know if a U.S. interstate exit will have a return entrance ramp?
