Hi Santosh,

Here is demo code for same.
  
for(Customobject__c obj : Trigger.new)
{
        if(String.isNotEmpty(obj.customPicklistField__c)  && obj.customPicklistField__c.split(';').size() > 3)
        {
                  obj.addError('You can not select more than 3 values in pick-list');
        }
}

Please let me know if this works.

Thanks
