In the article entitled La délire de la jungle, I came across the expression “sans crier gare”.
Des ânes traversent sans crier gare.
The expression “crier gare” means to shout out a warning to somebody. Hence the epxression “sans crier gare” means:
Without warning, out of the blue, unexpectedly
Hence we can translate the whole sentence as:
Donkeys cross unexpectedly.
