Seats for people with disabilities or the elderly.
A priority seat.
A disabled seat.
'A priority seat' is the politically correct term these days - to include people such as mothers with young children or pregnant women and ill people.
Informally in the UK, people quite usually just say, "The disabled seat" though, of course, it is not the seat itself that is disabled!
A priority seat は政治的にも正しい（差別的ではない）言葉として認識されている。お子様連れのお母さんや妊婦さん、病気の人も含めて、利用できます。
イギリスではカジュアルにthe disabled seatと言うことがよくありますが、椅子がdisabledというわけではもちろんございません。

We don't say disabled seat - the seat is not disabled. The person who is using it has priority seating.
The seat is restricted for use by the elderly or people with disabilities.
It is an access seat - they usually have wider access for people with crutches, a walking stick etc.

usually on buses or trains, the seats closest
to the exit are reserved for the elderly or those
with disabilities or for those with children.
they are placed here for ease of access, and it
is polite to move if a person of this nature boards
the bus to allow them to get in and out as easily as possible.
There are lots of areas set aside for those who are handicap and elderly. There are parking spots and seating in the airport, bus, and trains. Even in most bathrooms, there are special toilet seats for those who need additional assistance. In some instances, elderly and handicapped people are boarded before others on airplanes, trains, and busses.
