Here in the U.S it has been my experience that when you go into labour you go and see your obstetrician or his mid-wife and if they believe you are in actual labour they send you to the hospital, where you will be admitted. It’s nice because by the time you get there they are expecting you and have room ready.
My experience here in the US has been slightly different.
For starters, OB/GYNs can be women 
You have an OB/GYN or midwife team throughout pregnancy and for your delivery.
You phone your OB/GYN or midwife team if you think you are in labour, day or night. They do not ask you to go to their office. This has been my experience in two different hospitals, and with an OB team and MW team. This is the same whether you are privately insured or a Medicaid patient.
If out of office hours their answering service will have your OB/MW call you back. The advantage of a team practice is that someone will always be on call.
They assess how things are going, and will call the hospital where they have admitting privileges to warn of your arrival. It is your call in the final analysis whether to go in or wait at home, and they obv tell you to take traffic conditions into account, but they will advise you to go when contractions get to (for example) a steady five minutes apart, but this depends on your history if you have any.
Even so, they are normally banking on a gradual and steady progression to contractions two minutes apart. My own OB talked to me on the phone at about 8 o'clock the morning DD2 was born, and we agreed I would shoot for a noon arrival at the hospital, where she would be waiting. I was feeling ok, able to speak, was feeding DD1 and DS breakfast, but definitely in labour.
By 9 o'clock I was unable to speak and could barely walk. exH banged on a neighbour's door and asked if their teenage DD was willing to babysit DD1 and DS for a few hours, hustled me down two flights of stairs, into the car, and off we went. We passed another hospital on our way but decided since it was a Saturday (light traffic) we would continue to the one where my OB practiced, with fingers crossed. Waters broke in the reception area, I was triaged, taken straight to delivery suite and DD2 was born approx 40 minutes after we left home. A spotty young lab tech entered the room as I was starting to push, to do my admitting blood draw. I yelled, 'No way, get out!' The OB resident did a great job, taking orders from my OB on the phone. She arrived in time to supervise the mopping up and congratulate me on our choice of name (same as her sister's apparently).
