What does truncating SQL logs do?
Log truncation deletes inactive virtual log files (VLFs) from the logical transaction log of a SQL Server database, freeing space in the logical log for reuse by the Physical transaction log. If a transaction log is never truncated, it will eventually fill all the disk space allocated to physical log files.

Large database transactions, such as importing large amounts of data, can lead to a large transaction log file. Transaction log backups not happening fast enough causes the SQL log file to become huge. SQL log files also enlarge due to incomplete replication or availability group synchronization.
Is it safe to shrink SQL log file?
It’s safe, but do it at a quiet time when there’s low transactional activity. It’s recommended to shrink the log to its minimal size and then grow it to its normal size (this will ensure the correct number of VLFs (internal virtual log files) are created, which improves performance for logged commands).
