If I make a claim, will I automatically lose my NCD?

Not necessarily. All insurers in Singapore use a guide called the Barometer of Liability Agreement (BOLA) to determine how much each party is liable in an accident. The BOLA is designed to speed up claims processing. It does not diminish your right to contest liability under the law. Under the BOLA, your NCD will not be affected if your liability is 20% or less in an accident involving an identified vehicle. In all other cases, your NCD may be affected.
