某停车场车辆停放服务
收费标准
仅供参考，谢谢
| 车辆l类型 | 收费方式 | 收费标准 | 备注 | ||
|---|---|---|---|---|---|
| 1小时内停放时间 | 超过免费时间2小时内 | 超过两小时后每小时 | 不足一小时按一小时计算 | ||
| 小型 | 元/车.次 | 免费 | 3 | 1 |
1、24小时内，车辆连续停放跨两个收费时段的，车辆停放服务
费可累计收取，最高收费不得超过10元;车辆连续停放24小时以上
的，车辆停放服务费按实际停放时间计算。
2、连续停放跨两个收费时段的，可按两个时段的收费标准累加
收取。
3、对正在执行公务或任务的军车、警车、消防车、救灾抢险车、
市政工程(水、电、气、通信、照明、园林绿化等)抢修作业车、
环卫车等特种车辆的停放，免收机动车评放服务费。
